Question

ballistic pendulum: i was given mass of block and mass of bullet only. How do i find the maxium height if i don't have a velocity or how do i find a velocity without a height?

Answer 1

A ballistic pendulum is used for measuring bullet's velocity by measuring the amplitude (hieght) of pendulum. For this if we know the amplitude then we can apply conservation of energy and conservation of momentum method to find the velocity of bullet. Or we know the velocity of bullet then we can find Amplitude (hieght).

• But by knowing mass only without any information of velocity, energy or momentum its impossible to find hieght or velocity by knowing only masses.
