An ice skater pushes off, then glides straight across very smooth ice at nearly constant speed. After the push ends, what horizontal force is needed to maintain the glide?
A parachutist falls straight downward at terminal velocity. What is the relationship between weight and air resistance?
A soccer ball rolls right on grass and slows down. After the kick, which force changes its velocity?
A spacecraft far from planets moves in a straight line at 700 m/s with its engines off. What will its velocity be one hour later?
In a tug-of-war, the marker at the center of the rope stays at rest. Considering the rope section as the system, what is true of the horizontal pulls?
A worker pushes a heavy crate with 80 N to the right, but the crate remains at rest. What does static friction do?
A train travels north on a straight track at a constant 20 m/s. How do the engine force and total resistive force compare?
A hockey puck slides left at constant velocity on nearly frictionless ice. What is the horizontal net force on it?
A 1200 kg car travels straight at constant 25 m/s. The road pushes the car forward with +850 N. Taking forward as positive, what is the total resistive force?
