Question

a racing car initially at rest accelerates at a uniform rate of 5.5 M per second square for 10 seconds calculate number 1 the distance covered by racing car from start and number to final velocity in kilometre per hour

Answer 1

u=0
a=5.5 m/s2
t=10s
v=u+at=55m/s=55*18/5=198km/h
s=ut+at^2/2==550/2=275m
