Starting at a height of 2m 4 people push a sled down a 20* incline, cross 5m of ice and go up a 30*incline before coming to rest 3m above the ice. All four members of your team must be in the sled when it is sliding across the ice and up the 30* incline. Before starting you do the following tests:
You discover that on average a person can stand on an incline without sliding as long as the angle is less than or equal to 40*.
You let the sled slide down the 20* incline and discover that it takes 3 seconds for it to slide to the bottom of the incline. After which the sled slides a distance of 2m across the ice before stopping.
Mass of sled = 70 kgs
Mass of person=70kgs
Is it possible to do it and if not can you prove it?
Thanks.
(N.B both inclines are snow with same coefficent of friction.)
