Weight = 5 * 10^5 * 9.8 = 4.9 * 10^6 N
The net force is equal to the thrust force minus the sum of the weight and the air resistance.
Net force = 1.25 * 10^7 – (4.5 * 10^6 + 4.9 * 10^6) = 3.1 * 10^6 N
F = m * a
3.1* 10^6 = 5 * 10^5 * a
a = 3.1* 10^6 ÷ 5 * 10^5 = 6.2 m/s^2
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.
