If you drop your laptop (6 lbs or 2.72 kg); what is its acceleration as it hits the ground, meaning the acceleration that that takes to stop it from the impact speed, during the stopping distance. and how does this acceleration compare to what a human can safely endure without harm? How does it compare to the acceleration of other objects?
Homework Answers
For any object hitting the ground be it the laptop or human or any other object , If it is freely fall acceleration is always 9.8m/s^2 towards the ground
If there is some strong force F applied , the acceleration will be Force / mass of the object plus the gravitational pull . the gravitational acceleration 9.8m/s^2 may be incomparable to the acceleration due to applied strong force.
When an object hits the ground there is a collision and change in momentum . The change in momentum is the impact force multiplied by time of impact on the ground which equals to Impulse expression,( Impulse = F * t ) the impact force produces the acceleration. The impulse is equal to change in momentum.

A box (350 kg) sits inside the trailer of a semitruck traveling at a speed of 15 m/s (~ 33 mph). Suddenly, a car in front of the truck stops in the road. The driver of the truck hits the brakes to bring the truck to a stop. Assume that the coefficient of static friction µs = 0.7 between the box and the floor of the trailer. Assume g = 10 m/s2. When the truck is slowing down, what is...
