| What is the mass of a runner moving at the speed of 2.5 msec with a momentum of 200 kg m per sec? I would be really helpful if anyone can answer to that issue. I'm caught with this dilemma for last week and I'm not able to find houses answer for that situation. Any reaction will be highly appreciated. Thank you extremely considerably and have a fantastic working day. Apologies for my weak english language.
