PLEASE HELP SIMPLE QUESTION 90 POINTS A student and the waxed skis she is wearing

have a combined weight of 850 newtons.

The skier travels down a snow-covered hill

and then glides to the east across a snow-covered, horizontal surface.

2. Determine the magnitude of the normal force exerted

by the snow on the skis as the skier glides across the

horizontal surface.

3. Calculate the magnitude of the force of friction acting on the skis as the skier glides across the snowcovered, horizontal surface. [Show all work, including

the equation and substitution with units.]

I already know 2 is 850. But how do you get the coefficient of friction for 3. brainliest to best answer!

Will a heavier bowling ball hit pins better than a lighter bsll

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
