a body start from rest with an acceleration 2 m/s2 till it attaains the maximum velocity then retards with 3 m/s2. if total time taken is 10 second, then maximum speed attained is
1 Answersthe maximum speed attained will be 12m/s .
drawing the velocity-time graph will be helpful
a triangle will be formed
drop a perpendicular from the upper vertex to x-axis
now two triangles will be formed
since we know that the slope of v-t graph gives acceleration
apply tanΘ and get the answer

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.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
