Chapter 5, Problem 52GP

Your forehead can withstand a force of about 6.0 kN before fracturing, while your cheekbone can only withstand about 1.3 kN.

a. If a 140 g baseball strikes your head at 30 m/s and stops in 0.0015 s, what is the magnitude of the ball’s acceleration?

b. What is the magnitude of the force that stops the baseball?

c. What force does the baseball apply to your head? Explain.

d. Are you in danger of a fracture if the ball hits you in the forehead? In the cheek?

on an unknown planet, a 145 g baseball is hit so that it travels straight upward to reach a maximum height of 15.6 m after being struck by the bat. A fan observes that it takes 2.90 s for the ball to reach its maximum height.  A. what is the initial velocity of the baseball B. What is the acceleration due to gravity on this planet
A stuntman drives a car of mass 1125 kg east with a speed of 20 m/s.  a. If the car accelerates at a rate of –2 m/s 2 , how long will it take the car to go 50 m? b. The stuntman drives the car off an 80 m cliff while going 15 m/s. How long will it take the car to land? c. How far horizontally from the cliff will the car land?
A slug with a mass of mm = 16 g is shot out of a rifle that has length LL = 0.72 m. The slug spends tt = 0.14 s in the barrel.a. Calculate the magnitude of the slug's acceleration, in meters per second squared, as it travels through the rifle's barrel. You may assume the acceleration is constant throughout the motion. b. What is the numerical value of the net force in newtons acting on the slug?
