Solve the all parts of following problem:
Problem: A 65.0-kg snowboarder works on a half-pine event from top of one side of the semicircle (7.00 m radius) to the other side.
Part A: What is the minimum work that the snowboarder has to do in order to go up 1.50 m above the edge on the other side?
Part B: If the average kinetic friction between the snow and the board is 321 N, how much more work is required from the snowboarder?
I want help to determine how much more work is required from the snowboarder.
On a banked race track, the smallest circular path on which cars can move has a radius r1 =104 meter, while the largest has a radius r2 = 163 meter. Determine the smallest speed at which cars can move on this track without relying on friction

A vertical container with base area of length L and width W is being filled with identical pieces of candy,each with a volume of v and a mass m. Assume that the volume of the empty spaces between the candies is negligible.
An electron is accelerated during 2100 V from rest and then enters a uniform 1.60 T magnetic field. What is the minimum value this charge can experience? What is the maximum value of the magnetic force this charge can experience?
Four charges are located in a plane as follows: q1 = -5 uC at (4,0) m; q2 = -3 uC at (4,4) m; q3 = -4 uC at (0,4) m; q4 = -2 uC at (0,0) m. Find the magnitude and direction of the resultant field at (2,2)
