A particle moves in $x-y$ plane under the influence of a force $\overrightarrow{F}$ such that its linear momentum is $\overrightarrow{p}\left(t\right)=\hat{i}\cos \left(kt\right)-\hat{j}\sin \left(kt\right).$ If $k$ is constant, the angle between $\overrightarrow{F}$ and $\overrightarrow{p}$ will be                    [2024]

A player caught a cricket ball of mass 150 g moving at a speed of 20 m/s. If the catching process is completed in 0.1s, the magnitude of force exerted by the ball on the hand of the player is                    [2024]

A cricket player catches a ball of mass 120 g moving with 25 m/s speed. If the catching process is completed in 0.1 s then the magnitude of force exerted by the ball on the hand of player will be (in SI unit)              [2024]
