*47. | A semitrailer is coasting downhill along a mountain highway when its brakes fail. The driver pulls onto a runaway-truck ramp that is inclined at an angle of 14.0° above the horizontal. The semitrailer coasts to a stop after traveling 154 m along the ramp. What was the truck's ini- tial speed? Neglect air resistance and friction.

A car is parked on a steep incline, making an angle of 37.0 below the horizontal and overlooking the ocean when its brakes fail and it begins to roll. Starting from rest at t = 0, the car rolls down the incline with a constant acceleration of 4.00 m/s2, traveling 50.0 m to the edge of a vertical cliff. The cliff is 30.0 m above the ocean. Find (a) the speed of the car when it reaches the edge of the dill, (b) the time interval elapsed when it at rives there. (c) the velocity of the car when it lands in the ocean, (d) the total time interval the cat is in motion, and (e) the position of the car when it lands in the ocean, relative to the base of the cliff.

In the blizzard of ’88, a rancher was forced to drop hay bales from an airplane to feed her cattle. The plane flew horizontally at 160 km/hr and dropped the bales from a height of 80 m above the flat range, (a) She wanted the bales of hay to land 30 m behind the cattle so as to not hit them. Where should she push the bales out of the airplane? (b) To not hit the cattle, what is the largest time error she could make while pushing the bales out of the airplane? Ignore air resistance.
I am mostly just wondering about finding the velocity B. I know how to find tension after that. I got Vb= 4.214 m/s for the veloctity but I am not sure if I did it right. Hight initial is 0.702 m This was what I did (1/2)(5)(2^2)+(5)(9.8)(.702)=(1/2)(5)(Vf^2)

A small glider is coasting horizontally when suddenly a very heavy piece of cargo falls out of the bottom of the plane. You can neglect air resistance. Just after the cargo has fallen out O both the cargo and the plane speed up. the plane speeds up but the cargo does not change speed. None of these the plane speeds up and the cargo slows down. the cargo slows down but the plane does not change speed neither the cargo nor the plane change speed.
