Answer:

Acceleration = 9.8m/s²

Explanation:

Given the following data;

Initial velocity = 0m/s (since it's starting from rest).

Final velocity, v = 14.7m/s

Time, t = 1.5 seconds.

To find acceleration;

In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.

Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.

Mathematically, acceleration is given by the equation;

Substituting into the equation, we have;

Acceleration = 9.8m/s²

Therefore, the average acceleration of the golf ball is 9.8m/s².

Further explanation

Given:

initial velocity = u = 0 m/s

time taken = t = 1.5 seconds

final velocity = v = 14.7 m/s

Asked:

acceleration = a = ?

Solution:

v = u + atv=u+at

v - u = atv−u=at

a = (v - u) \div ta=(v−u)÷t

a = \frac{ v - u }{t }a=

t

v−u

a = \frac{ 14.7 - 0 }{1.5}a=

1.5

14.7−0

a = \frac{14.7}{1.5}a=

1.5

14.7

a = 9.8 \texttt{ m/s}^2a=9.8 m/s
