Newton’s Laws of Motion

A lift weighing $1000 \mathrm{kg}$ is moving upwards with an acceleration of $1 \mathrm{m} {\mathrm{s}}^{-2}$. The tension in the supporting cable is $\left(g=9.8 \mathrm{m} {\mathrm{s}}^{-2}\right)$

Three identical blocks of masses $m=2 \mathrm{kg}$ are drawn by a force $F=10.2 \mathrm{N}$ on a frictionless surface, then what is the tension (in $\mathrm{N}$) in the string between the blocks $B$ and $C$?

A player caught a cricket ball of mass $150 \mathrm{g}$ moving at a rate of $20 \mathrm{m} {\mathrm{s}}^{-1}$. If, the catching process is completed in $0.1 \mathrm{s}$, the force of the blow exerted by the ball on the hand of the player is equal to

A body of mass $m$ hangs at one end of a string of length $l$, the other end of which is fixed. It is given a horizontal velocity so that the string would just reach where it makes an angle of $60°$ with the vertical. The tension in the string at mean position is

Water from a hosepipe of radius $5 \mathrm{cm}$ strikes a wall at a speed of  $5 \mathrm{m} {\mathrm{s}}^{-1}$ normally and stops. The force exerted on the wall in newton is

 Why does a rider on horseback fall when the horse starts running all of a sudden?

A mass $1 \mathrm{kg}$ is suspended by a thread. It is (i) lifted with an acceleration of $4.9 \mathrm{m} {\mathrm{s}}^{-2}$, (ii) lowered with an acceleration of $4.9 \mathrm{m} {\mathrm{s}}^{-2}$. The ratio of tensions is

A force vector applied on a mass is represented as $\overrightarrow{F}=6\hat{i}-8\hat{j}+10\hat{k}$ and accelerates with $1 \mathrm{m} {\mathrm{s}}^{-2}$. What will be the mass of the body?

A car accelerates on a horizontal road due to the force exerted by

When a horse pulls a cart, the force that helps the horse to move forward is the force exerted by
