A baseball is hit off of a tee. The bat stays in contact with the ball for 25 ms. The speed of the ball after contact is 50 m/s. Assuming constant acceleration, what is the average force exerted by the bat on the baseball, expressed in terms of the weight of the baseball w? A) 204w

B) 19,600w

C) 2000w

D) 0.2w

What’s #16 asking me and how do i solve it?

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.
