The speed of a bullet can be measured by firing it at a wooden cart initially at rear and measuring the speed of the cart with the bullet embedded in it. Figure P4.80 shows a 12-g bullet fired at a 4.0-kh cart. After the collision, the cart rolls at 1.8 m/s. What is the bullet's speed before it strikes the cart?
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?
