In 10 second horizontal distance travelled by plane is 980 m and vertical distance is 490 m so angle is tan^-1 (0.5)

A plane is moving with 98m/s velocity.An object is released from it so it have acceleration of "g". So g=v/t so velocity of object will be V=gt V=9.8×10=98m/s Now using tan x = 98/98=1 So value of tan x =1 So value of tanx is 1when X=45°

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.

An object of mass m = 0.25 kg oscillates in a fluid at the end of a vertical spring of spring
constant kH = 85 N/m, see Fig.1. The effect of the fluid resistance is governed by the
damping constant b = 0.07kg/s.
(i) Find the period of the damped oscillation.
(ii) By what percentage does the amplitude of the oscillation decrease in each cycle?
