(I) A 0.145 -kg baseball pitched at 35.0 $\mathrm{m} / \mathrm{s}$ is hit on a horizontal line drive straight back at the pitcher at 56.0 $\mathrm{m} / \mathrm{s} .$ If the contact time between bat and ball is $5.00 \times 10^{-3} \mathrm{s}$ , calculate the force (assumed to be constant) between the balland bat.

In physics, a conservative force is a force that is path-independent, meaning that the total work done along any path in the field is the same. In other words, the work is independent of the path taken. The only force considered in classical physics to be conservative is gravitation.

In physics, the kinetic energy of an object is the energy which it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body in decelerating from its current speed to a state of rest. The kinetic energy of a rotating object is the sum of the kinetic energies of the object's parts.

force is equal to the rate of change of momentum. And so that's mass times. The rate of change of velocity, um, and Mass is 0.145 kilograms for time is five times 10 and negative three seconds. So for, um, Delta V, we have, um so we'll take the pictures direction are the direction had from the batter to the picture as the positive direction. Okay, and so 56 meters per second is final velocity. It's positive minus minus 35 meters per second. Cause of the ball is pitched towards towards the batter. Um, been so away from the picture and wreck by about a tender. And so this gives us 26 40 Newton's on. So since it's positive, uh, direction is toward the picture.
