The three blocks with weights as shown in the figure are placed on a 20o incline so that they are in contact with each other and at rest. Determine which, if any, of the blocks will move and the friction force acting under each. Assume that under blocks A and C, the coefficients of friction are fs = 0.50 and fk = 0.40 while under B they are fs = 0.30 and fk = 0.20
An athlete slides down from rest 40.0 meter along an icy hill which is 35 degrees from the horizontal. He then continues sliding on the level ice.
a) If the coefficient of kinetic friction between the athlete and ice is 0.20 (neglect air resistance) find speed (m/s) of the athlete at the foot of the plane.
b) find the distance (m) from the foot of the plane to the point where he has landed to the level ice
Note: Please express finals answers in significant figures and scientific notation only, thanks!!
Determine the acceleration of both if m1 = 11.0 kg, m2 = 18.0 kg andθ = 30°. The inclined surface is friction-free.
