Which of the following statement is correct?
Statement A: If the force varies with time then the net force is measured by the total change in momentum of the body.
Statement B: Change in momentum and impulsive force are numerically equal.

The variation in momentum with time, for a body under collision is shown in figure. The maximum & minimum instantaneous forces are respectively on these points:

Read the following statements and choose the correct option:
Statement: Newton's second law of motion gives the measurement of force. 
Reason: According to Newton's second law of motion, force is directly proportional to the rate of change of momentum. 

A particle of mass $0.3 \mathrm{kg}$ is subjected to a force $F = Kx$with $K = 15 \mathrm{N}/\mathrm{m}$, what will be its acceleration if it is released from a point $x = 20 \mathrm{cm}.$

The velocity-time graph of a ball of mass $20 \mathrm{g}$ moving along a straight line on a long table is given in figure.The force exerted by the table on the ball to bring it to rest is :

A force ‘F’ is applied on one end of a rope of length ‘a’. P and Q are two points of length ‘b’ from nearest end. The ratio of tensions in string at P & Q is :

Which among the following is the correct statement?
A. When an object is thrown upwards, then in any case whether going upwards or coming downwards its speed will remain the same. 
B. The weight of any object cannot be zero. 
 

A dynamometer D is attached to two masses $m_1=3 \mathrm{kg}$ and $m_2=5 \mathrm{kg}$. Forces of $f_1=9 \mathrm{N}$ and $f_2=25 \mathrm{N}$ are applied to the masses as shown.

The dynamometer will read :

In a two body collision, the momentum is varying with time as shown in graph. The instantaneous force is maximum at: 

Two similar trucks are moving with the same velocity on a road. One of them is loaded while the other is empty. Which of the two will require a larger force to stop it?
