Question

An object is moving along a straight line with uniform acceleration. The following table gives the velocity of the object at various instants of time; Plot the graph.; From the graph.; (i) find the velocity of the object at the end of 2.5 seconds.; (ii) Calculate the acceleration.; (iii) Calculate the distance covered in the last 4 seconds.

Answer 1

Answer:

.intial speed=2m/s

time=2s

final speed=6

v=u+at

6=2+2a

4=2a

a=2m/s^2

now

intial speed =2m/s

time =2.5s

acleration =2m/s^2

v=u+at

v=2+2.5×2

v=2+5

v=7m/s
