You start pushing the cart and reach constant velocity. Thus you are pushing the cart withzero forceconstant non-zero forceO increasing forcedecreasing forceThe net force on the shopping cart iszeronon-zero and constantO increasing over timeO decreasing over time Suddenly a small child spilled some sticky liquid on the ground. Your cart wheel rolled over the liquid.This is a different scenario than before. However you continue rolling the cart ahead at constantvelocity. But now you are applyingO continuously increasing force.constant force as before the wheel ran over liquidO higher constant force than before the wheel ran over the liquid.O lower constant force than beforewheel ran over the liquid.

Two crates of fruit are released from the top of a ramp inclined at 30 degrees from the horizontal and 4.5 meter long. The two crates consist of an apple crate of mass 20 kg that is placed in front of a watermelon crate of mass 80 kg. The apple crate has a coefficient of friction of 0.20 while the watermelon crate has a coefficient of friction of 0.15. How long does it take the apple crate to reach the bottom of the incline if it needs to travel a distance of 4.5 meters?
The standing vertical jump is a good test of an athlete’s strength and fitness. The athlete goes into a deep crouch, then extends his legs rapidly; when his legs are fully extended, he leaves the ground and rises to his highest height. It is the force of the ground on the athlete during the extension phase that accelerates the athlete to the final speed with which he leaves the ground. A good jumper can exert a force on the ground equal to twice his weight. If his crouch is 60 cm deep, how far off the ground does he rise?
