A 1000 kg roller coaster is at the top of a 20 m hill initially moving at 5 m/s. It goes down the hill to ground level, then up a hill that is 10 m high, and then back down to 5 m above ground level. There is no friction between the roller coaster and the track. Calculate:

a) Initial Mechanical Energy of the Roller Coaster

b) the velocity of the roller coaster at the bottom of the 20 m hill (ground level)

The base of a 50-meter tower is at the origin; the base of a 50-meter tree is at (0, 50, 0). the ground is flat and the z-axis points upward. the following parametric equations describe the motion of six projectiles each launched at time t = 0 in seconds. (i) r (t) = (50 + t2)k (ii) r (t) = 2t2 j + 2t2k (iii) r (t) = 50 i + 50 j + (50 − t2)k (iv) r (t) = 2t j + (50 − t2)k (v) r (t) = (50 − 2t) i + 2t j + (50 − t)k (vi) r (t) = t i + t j + tk (a) which projectile is launched from the top of the tower and goes downward? at time t = , the projectile hits the ground at point (x, y, z) = . (b) which projectile hits the top of the tree?
