Question

A transport truck is travelling at 24ms -1 . As it reaches the outskirts of a town it changes its speed to 10ms -1 . Calculate the transport trucks acceleration if it takes 8 seconds to change speed.

Answer 1

Acceleration a =-1.75 m/s²

Step-by-step explanation:

Given:

Initial speed u = 24 m/s

Final speed v = 10 m/s

Time taken t = 8 sec

Find:

Acceleration a

Computation:

a = (v-u)/t

a = (10-24)/8

a = -14 / 8

Acceleration a =-1.75 m/s²
