Question 1 of 25A 2.0 kg block and a 3.0 kg block sit on a frictionless table, joined by a light string. A horizontal 10 N force pulls the 3.0 kg block, so both blocks speed up together. What is the tension in the string?
Question 2 of 25A car starts from rest and speeds up uniformly to 20 m/s in 5.0 s. How far does it travel in that time?
Question 3 of 25A small block is released from rest at the top of a frictionless ramp 1.8 m high. How fast is it moving at the bottom? (Use g = 10 m/s².)
Question 4 of 25A wooden block floats at rest in fresh water (density 1,000 kg/m³) with 60% of its volume below the surface. What is the density of the wood?
Question 5 of 25A 2.0 kg cart moving at 3.0 m/s collides with a 1.0 kg cart at rest, and the two carts stick together. What is their speed just after the collision?
Question 6 of 25A 30 kg child sits 2.0 m from the pivot of a seesaw. How far from the pivot, on the other side, must a 40 kg child sit for the seesaw to balance? (Ignore the board’s own weight.)
Question 7 of 25A 60 kg person stands on a bathroom scale in an elevator that is accelerating upward at 2.0 m/s². What does the scale read? (Use g = 10 m/s².)
Question 8 of 25A figure skater spinning on frictionless ice pulls her arms in close to her body and spins faster. What happens to her angular momentum and her rotational kinetic energy?
Question 9 of 25A boat heads straight across a river at 4.0 m/s relative to the water. The river flows at 3.0 m/s. What is the boat’s speed relative to the shore?
Question 10 of 25A spring with spring constant 200 N/m is compressed 0.10 m and then releases a 0.50 kg block on a frictionless floor. What is the block’s speed after it leaves the spring?
Question 11 of 25A block on a spring oscillates with a period of 0.80 s. The block is replaced with one that has four times the mass, and the same spring is used. What is the new period?
Question 12 of 25A 5.0 kg block rests without moving on a rough ramp tilted 30° above the horizontal. What is the magnitude of the static friction force on the block? (Use g = 10 m/s².)
Question 13 of 25Water flows through a horizontal pipe at 2.0 m/s where the cross-sectional area is 4.0 cm². The pipe then narrows to an area of 1.0 cm². Compared with the wide section, what are the speed and the pressure in the narrow section?
Question 14 of 25A 0.15 kg ball moving at 20 m/s hits a wall and bounces straight back at 20 m/s. What is the magnitude of the impulse the wall gives the ball?
Question 15 of 25A motor lifts a 50 kg crate 12 m straight up at constant speed in 6.0 s. What average power does the motor deliver to the crate? (Use g = 10 m/s².)
Question 16 of 25A mechanic pushes on a wrench with a 20 N force applied 0.50 m from the bolt, but the force makes a 30° angle with the wrench handle. What torque does the force exert about the bolt?
Question 17 of 25A planet has twice the mass of Earth and twice Earth’s radius. What is the gravitational field strength at its surface? (Earth’s is 10 N/kg.)
Question 18 of 25A stone is thrown horizontally at 6.0 m/s from the top of a cliff 20 m high. Ignoring air resistance, how far from the base of the cliff does it land? (Use g = 10 m/s².)
Question 19 of 25A ball on a string moves in a horizontal circle at constant speed. How much work does the string’s tension do on the ball during half a revolution?
Question 20 of 25A solid sphere and a thin hoop with the same mass and radius are released from rest side by side at the top of the same ramp and roll without slipping. Which reaches the bottom first?
Question 21 of 25A car rounds a flat, unbanked curve of radius 40 m at a constant 10 m/s. What is the smallest coefficient of static friction between the tires and road that lets it do so without skidding? (Use g = 10 m/s².)
Question 22 of 25An object at rest explodes into two pieces. A 1.0 kg piece flies off at 6.0 m/s. What is the velocity of the other piece, which has a mass of 3.0 kg?
Question 23 of 25A wheel with rotational inertia 2.0 kg·m² starts from rest. A constant net torque of 8.0 N·m acts on it for 3.0 s. What is its angular speed at the end of that time?
Question 24 of 25A 4.0 kg box slides across a rough floor at 5.0 m/s and comes to rest. How much work does friction do on the box?
Question 25 of 25A diver is 10 m below the surface of a freshwater lake (density 1,000 kg/m³). The air pressure at the surface is 1.0 × 10⁵ Pa. What is the absolute pressure on the diver? (Use g = 10 m/s².)
