Newton's Second Law of Motion

In how much time an object having mass of $100 \mathrm{kg}$ will speed up from $5 {\mathrm{ms}}^{-1} \mathrm{to} 10 {\mathrm{ms}}^{-1}$ if  $500 \mathrm{N}$ force will be applied to it

When we apply a force of $1 \mathrm{N}$, we can hold a body whose mass is approximately equal to

The change in momentum of a body in$0.01 \mathrm{s}$ is $10 \mathrm{kg} {\mathrm{ms}}^{-1}$. The force acting on it is

If an object of mass $2.5 \mathrm{kg}$ experience a force of $5 \mathrm{N}$, the acceleration produced by it is.

Figure shows four blocks that are pulled along a smooth horizontal surface. The masses of the blocks and tension in one cord are given. The pulling force $F$ is

For a body thrown vertically upwards, if the air resistance is taken into consideration, then the time of rise is

A diwali rocket is ejecting $0.05\mathrm{kg}$ of gases per second at a velocity of $400 \mathrm{m} {\mathrm{s}}^{-1}$. The accelerating force on the rocket is

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. 

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 machine gun fires a bullet of mass $40$ gram at a speed of $1200 \mathrm{m} {\mathrm{s}}^{-1}$. The man holding it can exert a maximum force of $144 \mathrm{N}$ on the gun. How many bullets can he fire per second at the most?

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:

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 :

An object of mass $10 \mathrm{gm}$ is moving with an acceleration of $10 \mathrm{m}/{\mathrm{s}}^2$. Force acting on the object will be:

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

A small block of material having relative density $\frac{1}{3}$ is immersed in a liquid and released. The block starts moving upwards with an acceleration $a$. The value of $a$ is :($g$ is the acceleration due to gravity)

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 :

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 $x = 20 \mathrm{cm}.$
