The car has an initial velocity of 23 m/s and a final velocity
of 0 m/s. Recall that for constant acceleration,
The car stops in 7 s, so the acceleration is

Answer:
2 seconds
Explanation:
The function of height is given in form of time. For maximum height, we need to use the concept of maxima and minima of differentiation.
Differentiate with respect to t on both the sides, we get
For maxima and minima, put the value of dh / dt is equal to zero. we get
- 32 t + 64 = 0
t = 2 second
Thus, the arrow reaches at maximum height after 2 seconds.
