Question

Akash starts from rest and accelerates at 3 metre per second square 5 seconds then continue with constant velocity calculate the distance covered in 15 seconds since it is start from rest​

Answer 1

Answer:

320 is the answer

Explanation:

s

1

=ut+(1/2)at

2

=0+

1

×5×8

=160 m.

The velocity attained in 8 seconds is given by

v=u+at

=0+5×8=40 m/s.

The distance traveled in the next 4 seconds is

s

2

=40×4=160 m.

So, the total distance traveled by the car is s

+s

=160+160=320 m
