24. Two trains are accidentally put on the same track so that they are on a head-on collision course. Train-A is moving at 28 m/s and can decelerate at -4 m/s2. Train-B is moving at 30 m/s and can decelerate at -5 m/s2. When the trains are 190 meters apart they spot each other and immediately apply their brakes. Do they collide?

Two locomotives 70 kilometers apart are travelling on the same track towards each other, Engine A moves at 22 kilometers per hour east and engine B moves at 13 kilometersper hour west. At the instant both trains begin moving, an annoying mutant fly beginsflying from engine A towards engine B at 33 kilometers per hour . The instant it touchesB, it turns around and flies back. It goes on this way until the two locomotives collideand the mutant fly is finally squashed. So, before its untimely demise, a) what is the total distance the fly flew? b) the time it took till it was eliminated and c) the average velocity of the fly? how can i find this please
The 25-Mg boxcar A 16m/s to the right is coasting on the horizontal track when it encounters a 9-Mg car B coasting at 2m/s toward it. If the two cars meet and couple together, determin common speed in m/s just after the coupling. Please see details below. Rounding numbers to 2 decimal places at the end.
1. a 100kg astronaut (including the space suit) becomes untethered during a space walk and drifts to a distance of 10m from the mother ship. To get back to the ship, he throws his 2.5kg tool kit away with an acceleration of 8.0ms-1 that acts over 0.50s. a) How does throwing the tool kit away help the astronaut in the situation? b) How large is the fact that acts on the tool kit and the astronaut? c) With that speed will the astronaut drift to the mother ship? d) How long will it take for the astronaut to reach the ship?

6. A particle is moving along a straight line. After t seconds the distance the particle has travelled is x cm, its velocity is v cms- and the acceleration a of the particle is given by the differential equation a = 0.035 v2 Given that when t= 0, then x = 0 and v= 22 cms-!, calculate the velocity of the particle when t = 2 seconds.
