A Physics homework problem based on projectile motion and reaction time
A missile is launched and travels at 309m/s. If the operator discovers that the missile is locked on the wrong target and must be detonated by remote signal before impact, how far will the missile travel if the operator’s reaction time to send...

Numerical Problem from Motion of Connected systems
Two blocks A and B of mass m1 and m2 respectively are kept in contact on a frictionless table.The experimenter pushes the block A from behind so that the blocks accelerate. If the block A exerts a force F on the block B,what is the force exerted by the experimenter on A. Incoming search terms:numericals on [...]

Solution to HC Verma Problem
“Referring to HC Verma Part 2, chapter 29, Electric field and potential, Q 69 I think that Force is inversely proportional to square of the distance between the charged particles, so acceleration is not constant and hence v*v = u*u + 2*a*s is not valid in this case. [...]
