Question

A lorry pulls forward after initially being stationary, it takes the lorry 40m to reach a speed of 8m/s, calculate the lorry’s acceleration.

Answer 1

0.8m/s²

Step-by-step explanation:

we know,

v² = u² + 2as

here v is final velocity, u is initial velocity, a is acceleration & s is distance travelled.

8² = 0² + 2*a*40

⇒ 64 = 80a

⇒a = 64/80 = 0.8m/s²
