A force of 10 N acts on a body of mass 0.5 kg for 0.25 second starting from rest. What is its momentum now?

A rocket with a lift-off mass $3.5 \times 10^4$ kg is blasted upwards with an initial acceleration of ${10 \, m \, s^{-2}}$. Then the initial thrust blast is

With what maximum acceleration can a fireman slide down a rope whose breaking strength is two third of his weight?

A cannon ball is fired with a velocity ${200\, m \, s^{-1}}$ at an angle of 60? with the horizontal. At the highest point of its flight, it explodes into 3 equal fragments, one falling vertically downwards with a velocity ${100\, m\, s^{-1}}$. The second is going vertically upwards with a velocity ${100\, m\, s^{-1}}$, the third fragment will be moving with the velocity

A 4 metre long ladder weighing 25 kg rests with its upper end against a smooth wall and lower end on rough ground. What should be the minimum coefficient of friction between the ground and the ladder for it to be inclined at 60? with the horizontal without slipping ? (Take $g = {10 \,m \,s^{-2}}$)

A stone tied at the end of a string 80 cm long is whirled in a horizontal circle with a constant speed. If the stone makes 25 revolutions in 14 s, what is the magnitude of acceleration of the stone ?

An object is kept on a smooth inclined plane of $1 $ in $ l. $ The horizontal acceleration to be imparted to the inclined plane so that the object is stationary relative to incline is

With reference to the figure showing a light inextensible string passing over a fixed frictionless pulley, the tension $T_2$ is

A stone of mass 0.3 kg attached to a 1.5 m long string is whirled around in a horizontal circle at a speed of 6 ms. The tension in the string is

A motor cycle is going on an overbridge of radius $R$. The driver maintains a constant speed. As the motor cycle is ascending on the overbridge, the normal force on it

A block $B$ is pushed momentarily along a horizontal surface with an initial velocity $v$ . If $\mu$ is the coefficient of sliding friction between $B$ and the surface, block $B$ will come to rest after a time

Which is true for rolling friction $\left(\mu_{r}\right)$, static friction $\left(\mu_{s}\right)$ and kinetic friction $\left(\mu_{k}\right)$ :

A can filled with water is revolved in a vertical circle of radius $4\,m$ and the water does not fall down. What must be the maximum period of revolution?

When a particle is rotating in a circle will happen:

In the figure shown a block of weight 10 N is resting on a horizontal surface (figure). The coefficient of static friction between the block and surface is force of 3.5 N will keep the block in uniform motion, once it has been set in motion. A horizontal force of 3 N is applied to the block then:
