Question

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

Answer 1

Explanation:

A =4 m . D= 10 sec.

A= m change into sec = 1hr=60 sec = 60sec ÷4 m= 15sec . 15 ×10= 150 m/ sec ...

Answer 2

Answer:

given

initial speed (u)= 0 m/s

acceleration (a)= 4 m/s

time (t)= 10 s

final seep (v)= u + at

                      = 0 + (4 m/s * 10 s)

                      = 40 m/s ans
