Determine how many boards the bullet will penetrate
A bullet moving at a speed of 1000 ft/s has its speed reduced to 900 ft/s when it passes through a board. Determine how many boards the bullet will penetrate before it stops.

The coefficient of friction between the load and the flat-bed trailer shown is 0.4. Knowing that the speed of the rig is 45 mi/h, determine the shortest distance in which the rig can be brought to a stop if the doesn't shift.
The barrel and tube are filled with water (to the top of the tube). Calculate the ratio of the hydrostatic force on the bottom of the barrel to the gravitational force on the water contained in the barrel. (You need not consider the atmospheric pr
Assuming a significance level of 0.05 -- that is, we will reject the null hypotheses if the probability of getting the sample results, assuming that ? does in fact equal 90, is less than 5%. - how do we proceed to test whether your suspicions of r

A Wooden box item sits on a horizontal wooden board. The coefficient of static friction between the box and the board is 0.5. You grab one end of the board and lift it up, keeping the other end of the board on the ground. What is the angle between
A 45-g bullet is fired with a velocity of 600 m/s into a wooden block which rests against a solid vertical wall. Knowing that the bullet is brought to rest in 0.001 second, determine the average impulsive force exerted by the bullet on the block.
The average weight loss was 16.7 lbs., with a sample standard deviation of 25.4. Do these results support the claim at the 10% significance level that the exercise regimen results in weight loss?
