Question

Calculate accelerationof the following. calcutale the acceleration of josh rding his biycle in a straight line that speeds up from 4 m/s to 6m/s in 5 seconds

Answer 1

Explanation:

Wooho Physics my favorite subject! And my 100th answer :)

We will use the formula

$\boxed{\tt{ Acceleration = \dfrac{v - u}{t}}}$

• Where v is Final velocity
• And u is Initial velocity.
• t is time taken.

In this question :-

• u is 4 m/s
• v is 6 m/s
• t is 5 seconds

Applying the formula:-

$\sf{ Acceleration = \dfrac{6 - 4}{5}}$

$\sf{ Acceleration = \dfrac{2}{5}}$

So, Acceleration is 0.4 m/s² is the answer.

Hope it helps :)
