Your forehead can withstand a force of about 6.0 kN before fracturing, while your cheekbone can withstand only about 1.3 kN. Suppose a 140 g baseball traveling at 35 m/s strikes your head and stops in 1.6 ms .Part A -
If a140 baseball strikes your head at 30 m/s and stops in 0.0015s , what is the magnitude of the ball's acceleration?
Part B -
What is the magnitude of the force that stops the baseball?
Part C -
What force does the baseball apply to your head? Explain?
Part D -
Are you in danger of a fracture if the ball hits you in the forehead? Cheek?
