Question

A car accelerates uniformly from 20km/hr to 40km/hr in 10 seconds.Calculate 1) acceleration 2)distance covered 3) define acceleration 4) write the SI unit of acceleration.. need a great answer

Answer 1

Explanation:

(i) accelaration= v-u/t

40-20/10=2m/sec saquare

(ii)s=ut+1/2at square

20×10+1/2×2×10×10

200+100 =300 m

(iii)the rate of change of velocity in fixed time is called acceleration.

(iv)meter per second square

Answer 2

Answer:

this is your answer hope it helps you
