A body start from rest and accelerate uniformly at 5mls° until it attain a velocity of 25mls. Calculate the time taken to attain this velocity

Answer 1

To calculate the time taken to attain the velocity, we can use the equation for uniformly accelerated motion:

v = u + at

Where:
v = final velocity = 25 m/s
u = initial velocity = 0 m/s (since the body starts from rest)
a = acceleration = 5 m/s²
t = time taken

Rearranging the equation to solve for time:

t = (v - u) / a

t = (25 m/s - 0 m/s) / 5 m/s²

t = 25 m/s / 5 m/s²

t = 5 seconds

Therefore, it will take 5 seconds for the body to attain a velocity of 25 m/s.
