In a downhill ski race, your final velocity is not affected very much by getting a running start, because the initial kinetic energy is small compared with the gain in gravitational potential energy on even small hills. however, you will finish the race much faster (which is more to demonstrate this, find the final speed and the time taken for a skier who skies 75 m along a slope that is 29°, measured from horizontal, in the following situations (you may neglect friction). 25% part (a) find the final speed (in ms) of the skier starting from rest. grade summa pes 0% 100% potential coso cotan asin acos0 atan0 acotan sinh cosh0nh0cotanh0 submissions attempts remaining: 4 % per attempt) detailed view degrees o radians submit hint i give up! hints: 096 deduction per hint. hints remaining: 3 feedback: 1% deduction per feedback. 25% part (b) how long (in s) does it take for the skier to reach the bottom of this hill starting from rest? là 25% part (c) find the final speed (in ms) ofthe skier starting with a speed of 2.50 m/s. 25% part (d) how long (in s) does it take for the skier to reach the bottom of this hill with a starting speed of 2.50 ms?

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:

To practice problem-solving strategy 10.1 for energy conservation problems. a sled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slides a distance d1 down the slope and then covers the distance d2 along the horizontal terrain before stopping. find the coefficient of kinetic friction μk between the sled and the ground, assuming that it is constant throughout the trip.
