Piles of snow on slippery roofs can become dangerous projectiles as they melt. Consider a chunk of snow at the ridge of a roof with a slope of 32 degrees.  a.) What is the minimum value of the coefficient of static friction that will keep the snow from sliding down? Express your answer using two significant figures.   b.) As the snow begins to melt, the coefficient of static friction decreases and the snow finally slips. Assuming that the distance from the chunk to the edge of the roof is 5.0 m and the coefficient of kinetic friction is 0.10, calculate the speed of the snow chunk when it slides off the roof. Express your answer to two significant figures and include the appropriate units.   c.) f the roof edge is 12.5 m above ground, estimate the speed of the snow when it hits the ground. Express your answer to two significant figures and include the appropriate units.

Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”
