an object of mass 10kg is projected from ground with speed 40m/s at an angle 60with horizontal the rate of change of momentum of object one second after projection in SI unit is

Dear Student,

Please find below the solution to the asked query:

The rate of change of momentum is equal to the force acting on the particle. Therefore,

$$\begin{gathered} \frac{dP}{dt}=F=mg=10\times 10 \\ \Rightarrow \frac{dP}{dt}==100 N \end{gathered}$$
