Question

Example 14 : A car starts from rest and moves along the x-axis with constant acceleration of 10 m/s^2 for 2 seconds. It then continues with constant velocity. What distance will it cover in 5 seconds since it started from rest? ​

Answer 1

Answer:

answer is t

Explanation:

because t for tiger

Answer 2

Answer:

Correct option is

A

320 m

s1=ut+(1/2)at2

     =0+21×5×82

     =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 

s2=40×4=160 m.

So, the total distance traveled by the car is s1+s2=160+160=320 m
