Question

Racing car has a uniform acceleration of 10 m per second square what distance will it cover in 90 seconds if it is

Answer 1

If it is start at rest, then initial velocity (u)=0 acceleration(a)=10m per second^2, time(t)=90s distance(s)=? s=ut+1/2at^2 =0×90+1/2×10×(90)^2 =1/2×10×90^2 =450m distance will it cover in 90 seconds = 450m
