A car accelerate from 18km/hr to 36km/he in 10 second.calculate acceleration and express in km/hrs and m/s

Answer»

Answer:

Acceleration= change in velocity /time

Change in velocity =36 - 18=18 km h=5 m/sec

Time = 5sec

Acceleration =5/5=1 m/se

Equation of motion, s= UT +(1/2) at2

U= 18 km/h =5m/sec

T=5sec

A= 1m/sec

S= (5*5) + (1/2*1*5*5)

S= 25 + 12.5 i. E s= 37.5 m
