Question

4. a) A racing car has a uniform acceleration of 5 M per second square. What distance will it cover in 20 seconds after starting from rest? b) What can you say about the motion of a body if: P) Its distance-time graph is a straight line. Q) Its speed-time graph is a straight line?​

Answer 1

Answer:

Given: 

Initial velocity is: u=0

Acceleration is: a=4 ms2

Time is: t=10 s

Using second equation of motion:

s=ut+21at2

s=0×10+21×4×102

   =0+200=200 m
