A roof worker loses his grip on his box of tools while working on a tall house. His box slides down the roof. The roof is angled at 29 degrees with the horizontal. The roof is made of a frictionless material. The box travels 5 m down the roof and then leaves the edge of it 12 m above the ground. a). Figure out the box's velocity as it leaves the house's roof? b). How far from the base of the house does the box hit the ground? c). By how much does the box clear the yard fence which is 1.8m tall and located 6.7m away from the base of the house? 1 TOOLS 5m 29° 12 m 1.8m 6.7m FENCE

A circus performer throws an apple toward a hoop held by a performer on a platform (Fig. P4.27). The thrower aims for the hoop and throws with a speed of 24 m/s. At the exact moment the thrower releases the apple, the other performer drops the hoop. The hoop falls straight down. a. At what height above the ground does the apple go through the hoop? b. If the performer on the platform did not drop the hoop, would the apple pass through it? Figure P4.27

Curling is a game similar to lawn bowling except it is played on ice and instead of rolling balls on the lawn, stones are slid along ice. A curler slides a stone across a sheet of ice with an initial speed vi in the positive x direction. The coefficient of kinetic friction between the stone and the curling lane is k. Express your answers in terms of vi, k, and g only. a. What is the acceleration of the stone as it slides down the lane? b. What distance does the curling stone travel?
