A car's bumper is designed to withstand a 6.48 km/h (1.8-m/s) collision with an immovable object without damage to the body of the car. The bumper cushions the shock by absorbing the force over a distance. Calculate the magnitude of the average force on a bumper that collapses 0.240 m while bringing a 940 kg car to rest from an initial speed of 1.8 m/s.

The front 1.20 m of a 1 400-kg car Ls designed as a crumple zone that collapses to absorb the shock of a collision. If a car traveling 25.0 m/s stops uniformly in 1.20 m, (a) how long does the collision last, (b) what is the magnitude of the average force on the car, and (c) what is the magnitude of the acceleration of the car? Express the acceleration as a multiple of the acceleration due to gravity.
(a) A 75-kg man steps out a window and falls (from rest) 1.0 m to a sidewalk. What is his speed just before his feet strike the pavement? (b) If the man falls with his knees and ankles locked, the only cushion for his fall is an approximately 0.50-cm give in the pads of his feet. Calculate the average force exerted on him by the ground during this 0.50 cm of travel. This average force is sufficient to cause damage to cartilage in the joints or to break bones.
18. Auto companies frequently tests the safety of the automobiles by putting them through crash tests to observe the integrity of the passenger compartment. If a 1000 kg car is sent down a cement wall with a speed of 14 m/s and the impact brings it to a stop in 8.00 x 10^-2 s, with what average force is it brought to rest? *Use g=9.8 a. 145 000 N b. 212 000 N c. 315 000 N d. 175 000 N e. 423 000 N
A batter hits a 0.334 kg basball that was approaching him at 23.4 m/s and, as a result, the ball leaves the bat at 30.5 m/s in reverse of its original direction. the ball remains in contact with the bat for 24 ms. what is the magnitude of the average force exerted by the bat on the ball?
A 149-g baseball is dropped from a tree 15.0 m above the ground. a) With what speed would it hit the ground if air resistance could be ignored? b) If it actually hits the ground with a speed of 8.00 m/s , what is the magnitude of the average force of air resistance exerted on it?
A 105-kg rugby player is initially running at 7.5 m/s in the positive direction, but collides head-on with a padded goalpost and experiences a backward force of 1.76 × 104 N for 5.55 × 10–2 s. Calculate the final velocity in the horizontal direction of the rugby player, in meters per second. vf =
A mass m1= 3kg slides down slippery ramp, reaching a speed v=9 m/s at the bottom.After reaching the level ground m1 collides with mass m2= 4kg at bottom, sticking together in a perfectly inelastic collision. The combined mass then slides over a floor, finally coming to rest after travelling a horizontal distance x= 6m. a.) What is the force of friction between the combined masses and the floor? b.) What is the coefficient of kinetic friction between the floor and masses?
The great limestone caverns were formed by dripping water. (a) If water droplets of 0.03 mL fall from a height of 5 m at a rate of 10 per minute, what is the average force exerted on the limestone floor by the droplets of water during a 1-min period?
In the figure, the girl on the sled, weighing 70 lb, leaves point A from rest and goes down a 2% icy slope (assume no friction). She collides with her friend, weighing 60 lb, at point B, 200 feet down the slope. After colliding, they travel together down the slope on the sled. The slope is maintained, but the ice is a little rougher, with a coefficient of friction of μk = 0.15. a) How fast will they be moving immediately after they collide? b) Will they come to a stop after the collision? If so, how far will they travel until they do? If not, what will their acceleration be?
A 0.663-kg ball, initially moving with a speed of 3.09 m/s, bounces off a wall and then moves with a speed magnitude half of its original directed in the opposite direction. If the ball is in contact with the wall for 5.4 ms, what is the magnitude of the average force that the wall exerts on the ball? Express your answer in two decimal places, in Newtons.
You and your friend Peter are putting new shingles on a roof pitched at 23 ∘ . You're sitting on the very top of the roof when Peter, who is on the edge of the roof, 5.2 m away, asks you for the box of nails. Rather than carry the 2.3 kg box of nails down to Peter, you decide to give the box a push and have it slide down to him. If the coefficient of kinetic friction between the box and the roof is 0.52, with what speed should you push the box to have it gently come to rest right at the edge of the roof?
A 4.0-g bullet leaves the muzzle of a rifle with a speed of 340 m/s. What force (assumed constant) is exerted on the bullet while it is traveling down the 0.83-m-long barrel of the rifle? N
