Question

A bus accelerates uniformly from 40m/s to 20m/s in 10s. Calculate acceleration.

Answer 1

Answer:

u=20m/s

v=40m/s

t=10s

$a = \frac{v - u}{t}$

$a = \frac{40 - 20}{10}$

$a = \frac{20}{10}$

a = 2m/s²

Answer 2

Explanation:

a1 = 40m/s

a2 = 20m/s

T = 10s

a = v2-v1/t

= - 20/10

= 2m/s2
