Question

A car accelerates uniformly from 36km/h to 72 km/h in 20 s. Calculate acceleration

Answer 1

Acceleration = change in velocity / time taken
first of all,
Changing km/h to m/s

Acceleration = (20-10)/20 = 0.5 m/s².

Answer 2

• Acceleration = change in velocity / time taken

first of all

• Changing km/h to m/s

Acceleration = (20-10)/20 = 0.5 m/s².
