Question

A car accelerates uniformly from 18 km h to 36km h in 5 sec calculate acceleration in (i)km/h (ii)m/s

Answer 1

Answer:

because t is 5 sec and intial velocity is 5m/sec and finial velocity is 10m/sec than acc. is-

v=u+at

10=5+a(5)

10-5=a(5)

5/5=a

hence a=1m/sec^2

Answer 2

Answer:

36-18/5=3.6KM/HR , 36-18/5=3.6KM/HR, 3.6*5/18
