Find the acceleration of a \(2\) kg block acted upon by a net force of \(10\) N.

A 0.2 kg ball is thrown vertically upwards with an initial velocity of \( 10 \, \text{m/s} \). What is the maximum height reached by the ball? (Acceleration due to gravity \( g = 9.8 \, \text{m/s}^2 \))

The variation of stopping potential for metals A, B, C and D with frequency of incident radiation is as shown in the figure. For which metal, stopping potential is higher for lower values of threshold frequency (\(\nu_0\))? [The frequency of incident radiation \(\nu\) is same.]

A bullet of mass $20\,\text{g}$ moving with a velocity of $200\,\text{m/s}$ strikes a target and is brought to rest in $\left(\dfrac{1}{50}\right)^{\text{th}}$ of a second. The impulse and average force of impact are respectively

Two masses \( M_1 \) and \( M_2 \) are accelerated uniformly on a frictionless surface as shown in figure. The ratio of the tensions \( \left( \frac{T_1}{T_2} \right) \) is

The motion of a rocket in upward direction with high speed is based on the principle of conservation of

A ball at rest falls vertically on ground from a height of 5m. The coefficient of restitution is 0.4. The maximum height of the ball after the first rebound is

A block of mass $4\,\text{kg}$ is placed on a horizontal surface having coefficients of static and kinetic friction as $0.5$ and $0.4$ respectively. If a force parallel to the horizontal surface of $4\,\text{N}$ is applied to the body, then the force of friction acting on the body will be

A metal ball of mass 2 kg moving with a speed of 10 m/s had a head-on collision with a stationary ball of mass 3 kg. If after collision, both the balls move together, then the loss in kinetic energy due to collision is

A large open tank containing water has two holes to its wall. A square hole of side \( a \) is made at a depth \( y \) and a circular hole of radius \( r \) is made at a depth \( 16y \) from the surface of water. If equal amount of water comes out through both the holes per second, then the relation between \( r \) and \( a \) will be
