I two particle one with initial velocity 20m/s and another with 4m/s^2 then who leads initially
1 Answer
SARAVANAN GANESAN
The particle which starts with a velocity of 20m/s will take the initial lead upto 5 seconds. Then @ time =5 seconds both will be in the same distance from the start point. When time exceeds 5 seconds, the particle which had started with an acceleration of 4m/s^2 will take a lead. This can be inferred from the plot of distance vs time graph of the two particles. In the graph it can be observed that the particle which started with a velocity of 20m/s will be a straight line plot with some angle with the x-axis while the particle with an acceleration of 4m/s^2 will be parabolic in nature.

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

the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
