I've done 3 and 4 just want a clarification that it's right. Q3) Maxim, of mass 70kg, is running at 3.5ms1 when he jumps on a skateboard, of mass 2.2kg, travelling at 0.8 ms1 in the same direction. i. Calculate their new combined velocity. Q4) Maxim is on his skateboard again travelling at 6ms1 in the opposite direction to which his hat is pointed. He then leaps off the skateboard. If the skateboard’s velocity after the leap was 0.5ms1, find Maxim’s velocity post leap. (Mass of skateboard = 3kg, mass of Mr VT = 70kg). I need help with this question: Q5) Maxim is on his skateboard again, travelling at 4ms1 to the right. He then leaps off the skateboard. If the distance between Maxim and the skateboard was increasing at a rate of 4 metres per second, find Maxim’s velocity post leap. (Mass of skateboard = 3kg, mass of Mr vT = 70kg). (There are two solutions to this problem, explain what both mean in this situation). Last edited by skipjack; March 18th, 2017 at 11:26 PM.
