The mass of cart 1 was 1.10kg and mass of cart 2 is what's being solved for. they were next to each other and a spring was activated and the two carts moved away from each other and produced these readings. cart 1= v1: .75 m/s and cart 2= v2: .34m/s. what's the mass of cart 2

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?
