Question

a particle is under uniform motion it covers a total distance of 3000m before accelerating at 4m/s2 it continues to move with a uniform acceleration of 4m/s2 for the next 10 minutes if the total time taken for the journey was 15 minutes, calculate the following :
(i)the velocity of the object during the uniform motion (ii)the final velocity of the object at the end of 15 minutes (iii)average speed of the particle

Answer 1

Answer:

initial velocity =u

final velocity = v

v squared= u squared +2 aS s=displacement

=0 +2×4×3000
