Mechanics> A particle is moving with a uniform accel...

A particle is moving with a uniform acceleration along a straight line. Its velocities at A and B are respectively 7m/s and 17m/s^. M is the mid point of A and B. If t1is the time tajen to go from A to M and t2 is the time taken to go from M to B. Then what would be the ratio of t1/t2?
It’s answer is 3:2 but I am not getting the solution May you please help me out...

given conditions in the question are

particle is having uniform velocity.

velocity at A is 7m/s

velocity at B is 17m/s

M is midpoint of AB. so let us consider the distance between AB is “d”

therefore distance between AM is d/2 and distance between MB is d/2

here t1 is the time taken to reach A to M.

so velocity=displscement /time

time= displacement / velocity

for case AM

t1 =d/2*7 (*means multiplication)

similarily t2=d/2*17

t1/t2= 17/7 (on solving)

therefore the solution is t1/t2= 17/7

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.
