UAB PH201 student on Spring Break decides to test what she has learned about Newton's Laws on the ski slope. The 57 kg UAB student skier is on a smooth frictionless ski slope which is at an angle of ? = 18.6 degrees with the horizontal. If the skier starts from rest, what is her speed after 2.5 seconds?

Question
A UAB PH201 student on Spring Break decides to test what she has learned about Newton's Laws on the ski slope. The 57 kg UAB student skier is on a smooth frictionless ski slope which is at an angle of ? = 18.6 degrees with the horizontal. If the skier starts from rest, what is her speed after 2.5 seconds?
Expert Solution

Step 1
mass = m = 57kg
initial speed = V0 = 0 m/s
time = t = 2.5 Seconds
angle = 18.6 degrees
force along the incline F = m g sin
acceleration = a = F/m
