Bart Simpson is planning to jump a Cadillac on his skateboard. The ramps at either end of the car will be planks of wood resting on saw horses 1.00 m high. The Cadillac is 5.00 m long and its roof has a height of 1.60 m above the street. For maximum dramatic effect (and minimum chance of injury) Bart wants to just barely clear the roof and just barely make it to the down ramp. (a) How long should each plank of wood be? (b) How fast must Bart be going when he reaches the end of the up ramp? (P.S. Why is this the least injury prone way to jump the Caddy?)
The answer should be (a) 2.31 m and (b) 7.92 m/s. (but there is a small possibility that those answers could be wrong... but they shouldn't be)
