Cara is skiing down a hill. Her total mass (including the skis) is 70.4 kg. When she reaches the bottom of the ski slope, and the ground becomes level, she is moving at 6.22 m/s. The coefficient of friction between her skis and the snow is 0.114. How fast will Cara be moving 2.95 seconds after reaching the bottom of the slope? 1.12 m/s 3.30 m/s 2.92 m/s 2.16 m/s

Cara is skiing down a hill. Her total mass (including the skis) is 70.4 kg. When she reaches the bottom of the ski slope, and the ground becomes level, she is moving at 6.22 m/s. The coefficient of friction between her skis and the snow is 0.114. How fast will Cara be moving 2.95 seconds after reaching the bottom of the slope?
 
1.12 m/s
 
3.30 m/s
 
2.92 m/s
 
2.16 m/s

 

Expert Solution
Step 1

Given data-

Mass of Cara is M=70.4 kg

Initial velocity of Cara is v0=6.22 m/s

Coefficient of friction is given by μk=0.114

Time interval after which the velocity is required to be calculated is t=2.95 s

In this case when Cara reaches the ground level the only force acting on her is frictional force.
