Question

A bus increases its speed 20km/h to 50km/h in 10s . Find its acceleration

Answer 1

this is tbe answer you want

Answer 2

u = intial velocity = 20 km/ h = 5.56m / s
v = final velocity = 50 km/h = 13.89m/s
t = time = 10s

acceleration = final velocity - initial velocity / t
= 13.89 - 5.56/ 10
= 8.33 / 10
= 8.33/10 x 100/100
= 833/ 1000
= 0. 833m/s²
