Question

car starts from rest and moves along y axis with constant acceleration of 10 metre per second square for 10 seconds if it continues with constant velocity what is time it will cover in 24 second (a) 500 metre (B)1400m (C) 1900m(D)3300m​

Answer 1

Answer:

Correct option is

A

320 m

s

1

=ut+(1/2)at

2

=0+

2

1

×5×8

2

=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

1

+s

2

=160+160=320 m
