Question

Car racing car has a uniform acceleration of 4 metre per second what distance will it cover in 10 seconds after the start

Answer 1

Answer:

200 m

Explanation:

first of all it will be 4 m/s2

now u = 0

t= 10 s

a = 4 m/s2

now s = ut + 1/2 at2

= 0×10 + 1/2 ×4×100

= 200 m

Answer 2

Answer:

200m

Explanation:

a = 4m/s²

u = 0m/s²

t = 10s

s = ?

By 2nd equation of motion

s = ut + 1/2at²

s = 0×10 + 1/2×4×100

s = 0 + 4×50

s = 200m

So, the distance covered by a racing car in 10 seconds with an accelerartion of 4m/s² is 200m
