Question

A car accelerates uniformly from 18 Km/h in 5 minutes .The acceleration is ​

Answer 1

Answer:

Initial speed = u = 18 km/hr = 5 m/s. Final sped = v = 36 km/hr = 10 m/s. acceleration a = (v-u)/t = (10-5)/5 = 1 m/s2. Distance travelled S = u t + (1/2) a t2 = 5×5 + (1/2)×1×52 = 37.5 m.

Answer 2

Answer:

Acceleration=v-u/t

Here,

v= 36km/h

u=18km/h

t=5min= 1/12h

A-36-18/1/12

=216km/h2
