If 30 g of dough is taken will its mass change after applying force?

A ball of mass 0.2 kg is thrown vertically upwards by applying a force by hand. If the hand moves 0.2 m while applying the force and the ball goes upto 2 m height further, find the magnitude of the force. (Consider g=10m//s^2 ).

STATEMENT - 1 : A monkey climbing down a massless rope with magnitudes of acceleration lesses than his weight is applying force onrope lesser than its weight . and STATEMENT -2 : Force applied a body equals product of its mass and its acceleration .

Find out the work done when a force of 30 N displaces a body through 8 m in the direction of the applied force.

A hollow sphere of mass 1 kg and radius 10 cm is free to rotate about its diameter. If a force of 30 N is applied tangentially to it, its angular acceleration is (in rad/ s^(2) )

A force exerts an impulse I on a particle changing its speed from u to 2u. The applied force and the initial velocity are oppositely directed along the same line. The work done by the force is

A particle of mass 70 g, moving at 50 cm/s , is acted upon by a variable force opposite to its direction of motion. The force F is shown as a function of time t (a) its speed will be 50 cm/s after the force stops acting (b) its direction of motion will reverse (c) its average acceleration will be 1 m//s^2 during the interval in which the force acts its average acceleration will be 10 m//s^2 during the interval in which the force acts

A mass of 100 g strikes the wall with speed 5 m//s at an angle as shown in figure and it rebounds with the same speed it the contact time is 2 xx 10^(-3) sec . What is the force applied on the mass by the wall :

Consider a wire of length l, area of cross section A, and resistivity rho with resistance 10 Omega . Its length is increased by applying a force, and it becomes four times of its original value. Find the changed resistance of the wire.

A body of mass 5 kg starts from the origin with an intial with an intial velocity vec (u) = 30hat(i) + 40hat(j). . If the body collides with a wall and after collision its velocity becomes vec(v) = - 30 hat (i) + 40 hat (j) , then what is change in momentum of body ?
