Question

v) What will be the result when each term of sin20 + cos²0 = 1 is divided by sin?0?​

Answer 1

Step-by-step explanation:

By Newton's second law

Force is propotional to rate of change of momentum and we finally have

F = dp/dt =d (mv)/dt = dm/dt*v+ m*dv/dt (But as per Einstein’s equation mass can be assumed to be constant at velocities <<< speed of light ) so this equation can be simplified to

=m*dv/dt = ma

Hence force required is equal to mass*acceleration = 50kg * 2ms
