Hey everyone;
I am a grade 12 student and I am totally stuck on this question and would appreciate your help. I don't want just the answer, I need help with the steps so that I understand how to do this type of problem.
Here's the question:
A police officer arrives at the scene of a collision of the two snowmobiles to find both drivers unconscious. When two vehicles collided, their skis became entangled and the two snowmobiles remained locked together as they skidded to a stop. One driver was thrown clear of the mishap, but the other driver remained in the drivers seat. The posted speed limit in the area is 60km/h. One witness described how driver A was thrown horizontally at a constant speed from his seat (0.5 m above the snow surface) to his final resting position.
the initial angle between driver A and Driver B is 30 degrees
Driver A was thrown 8m
Mass of Driver A 80kg
Mass of driver B 90kg
Mass of vehicle A 270 kg
Mass of vehicle B 310kg
Before collision: Vehicle B East30degrees North Vehicle A East
Direction of entangles vehicles after collision East 15 degrees North
length if final skid 18m
displacement of driver A from point of impact: 8m
Time from impact to end skid 2.5s
I need to determine the initial velocities of both snowmobiles.
here is a picture of the question:
Thank you so much in advance. Again, I'm not fishing for answers, I'm in grade 12 and what i don't learn will come back to haunt me in university
