Impact Force - Engineering ToolBox

The impact on a human body can be difficult to determine since it depends on how the body hits the ground - which part of the body, the angle of the body and/or if hands are used to protect the body and so on. For this example we use an impact distance of 3/4 inch (0.0625 ft) to calculate the impact force: F max = 2 (800 ft lb) / (0.0625 ft)

Calculating Friction - Force

Question 2: A body of mass 40kg is given an acceleration of 10m/s 2 on horizontal ground for which the coefficient of friction is 0.5. Calculate the force required to accelerate the body. (Take g = 10m/s 2) Solution. Notice that the body is accelerated, which means the force that acted on it is more than the limiting frictional force.

Inclined Planes

Now the normal force can be determined to be 849 N (it must balance the perpendicular component of the weight vector). The force of friction can be determined from the value of the normal force and the coefficient of friction; F frict is 255 N (F frict = "mu"*F norm = 0.3 • 849 N). The net force is the vector sum of all the forces.

Forces between Bat and Ball

The impact between bat and ball is an extremely violent one, in which the bat imparts a huge force on the ball thereby causing it to change directions and gain speed. Consider a baseball weighing 5.125oz (mass = 0.145kg) which approaches the bat at a speed of 90mph (40.2m/s).

Since $text{force = mass}timestext{acceleration}$, is it right to say that an object traveling at a high constant velocity (zero acceleration), exerts zero force upon impact with a stationary object? I understand that upon impact, the projectile decelerates rapidly from initial velocity down to zero.
