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
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.
