Question

A car acquires a velocity of 72 km/h in 10 seconds starting from rest. Find: 1. acceleration 2.the average velocity 3. the distance travelled in this time

Answer 1

Answer:

1) 2m/s2

2) 10m/s2

Distance = 100m

Explanation:

1) A = v-u/t 72×5/18=20m/s

20-0/10=2m/s2

2) avg. velocity = v-u/2=20-0/2=10 m/s2

3) s= ut + 1/2at2

0+1/2×2×10×10

100 m
