Question

a racing car as uniform acceleration 4m/s2 what distance will it cover in 10 sec after start

Answer 1

Here's the solution. Hope it helps.

Answer 2

u = 0
t = 10 sec
a = 4 m/sec²

as we know, distance covered = ut + 1/2 × at²
                   = 1/2 × 4 × 100
                   = 200 m.

so, if the acceleration of the racing car is 4 m/sec², then after start, it will cover 200 m in 10 sec.
