Question

a racing car has a uniform acceleration of 4 m/s what distance will it cover in 10 s after start?

Answer 1

if the racing car started at rest,

u = 0 m/s

and also

a = 4 m/s²

t = 10 s

now, we know that

s = ut + (1/2)at²

or

s = 0 + (1/2)x4x10²

thus, distance travelled will be

s = 200m
