Question

A boy is running with a velocity of 10m/s. If his velocity becomes 40 m/s after 5 minutes. Calculate his acceleration. pls do it

Answer 1

Hello, here's your answer:

If t = 5mins, t = 60 x 5 = 300s

If a = v-u/t,

a= 40 - 10/300

a=30/300 = 1/10= 0.1m/s^2

Hence, the rate of acceleration is 0.1m/s^2

Answer 2

Given :

• Initial Velocity (u) = 10 m/s

• Final Velocity (v) = 40 m/s

• Time (t) = 5 minutes = (5×60) = 300 seconds

To Find :

• Acceleration (a)

Solution :

We know that, acceleration is measure of the change in velocity of an object per unit time.

★ Acceleration = Final Velocity - Initial Velocity/Time taken

→ a = $\sf\dfrac{40-10}{300}$

→ a = $\sf\dfrac{3\cancel0}{30\cancel0}$

→ a = $\sf\cancel\dfrac{3}{30}$

→ a = 0.1 m/s²

$\therefore$ Acceleration produced is 0.1 m/s²
