You have to catch a falling box of light bulbs with a mass of 10
kg and bring the box of light bulbs to rest without breaking, while
the box of light bulbs was falling with a velocity of 5 m/s.
What is the minimum amount of time you should use to stop the bulbs
from moving if they will break with only 150 N of force?

Climbing ropes stretch when they catch a falling climber, thus
increasing the time it takes the climber to come to rest and
reducing the force on the climber. In one standardized test of
ropes, an 80 kg mass falls 4.8 m before being caught by a
2.5-m-long rope.
If the net force on the mass must be kept below 11 kN, what is
the minimum time for the mass to come to rest at the end of the
fall?

A wagon is moving with a velocity of -2.0 m/s while having a 20 kg mass on top of it. There is a force applied to the wagon over a distance of 1.25 m. It then comes to a stop with a velocity of 0m/s. Please answer the questions. Show all work. 1. What is the total work done on the wagon? 2. What was the average force applied to the box to bring it to a halt?

You are pulling a 6.8 kg box with rope with a force of 5.5 N. The rope is 35° above thehorizontal. For a while you are pulling across ice that is very smooth. Later you reach a patch of snow which has a kinetic coefficient of friction of 0.2 and a static coefficient of friction of 0.35 with the box. A)Draw the free body diagrams for the box when it is on the ice and when it is on the...

A box rests on top of a flat bed truck. The box has a mass of m = 20 kg. The coefficient of static friction between the box and truck is mu_s = 0.86 and the coefficient of kinetic friction between the box and truck mu_s = 0.67. The truck accelerates from rest to v_f = 19 m/s in t = 12 s (which is slow enough that the box will not slide). What is the acceleration of the box?...

m A box rests on top of a flat bed truck. The box has a mass of m = 16 kg. The coefficient of static friction between the box and truck is is = 0.82 and the coefficient of kinetic friction between the box and truck is Hk = 0.64. 1) The truck accelerates from rest to Vp = 19 m/s in t = 13 s (which is slow enough that the box will not slide). What is the acceleration...
