where
is the ball's initial speed and
.
c. At its highest point, the ball has 0 vertical speed. This occurs when

d. Recall that

so that at its highest point,

e. This is just twice the time it takes for the ball to reach its maximum height,
.
f. The ball's horizontal position after time
is

so that after the time found in part (f), the ball has traveled

Answer:
F_suv= 49050 N
Explanation:
We are told that a 2000 kg car moving down the road runs into a 5000 kg stationary suv. The car applies a force of 1400 N on the suv.
Now, according Newton's first law of motion, an object will continue in it's present state of rest except it is acted upon by an external body.
This means the force acting on the stationary Suv is force of gravity.
Thus; F_suv = 5000 × 9.81
F_suv= 49050 N
