Explanation:
Given parameters:
Acceleration = 15m/s²
Initial velocity = 0m/s
Final velocity = 50m/s
Unknown:
Time taken for the acceleration = ?
Solution:
To solve this problem, we must understand that acceleration is the rate of change of velocity with time.
Mathematically;
a =
a is the acceleration
v is the final velocity
u is the initial velocity
t is the time taken
So;
15 =
15t = 50
t = 3.33s
