Hi,
Good day. I enjoy watching your physics videos, but I have a question and was wondering if you can answer it for me showing the working. the question is as follows:
A flat truck of mass 400kg is moving freely along a horizontal track at 3.0ms-1. A man moving at right angles to the track jumps on to the truck causing its speed to decrease by 0.5ms-1. What is the mass of the man?
Please reply as soon as possible thank you!
