A 5-gram [g] rubber ball is released from a height of 8 meters [m] above a flat surface on the moon. Gravitational accelerati
on on the moon is 1.62 meters per second squared [m/s2]. Assume that no energy is lost from frictional drag. What is the velocity, in units of meters per second [m/s], of the rubber ball the instant before it strikes the flat surface?

Answer:
The gazelles top speed is 27.3 m/s.
Explanation:
Given that,
Acceleration = 4.2 m/s²
Time = 6.5 s
Suppose we need to find the gazelles top speed
The speed is equal to the product of acceleration and time.
We need to calculate the gazelles top speed
Using formula of speed
Where, v = speed
a = acceleration
t = time
Put the value into the formula
Hence, The gazelles top speed is 27.3 m/s.
