An automobile with a mass of 1020.00 kg has 3.96 m between the front and rear axles. Its center of gravity is located 0.409 m behind the front axle. With the automobile on level ground, determine the magnitude of the force from the ground on: a. each front wheel (assuming equal forces on the front wheels)
b. each rear wheel (assuming equal forces on the rear wheels).

Afaulty model rocket moves in the xy-plane (the positive y direction is vertically upward). the rocket's acceleration has components ax(t) = ? t2 and ay(t) = ? ? ? t, where ? = 2.50 m/s4 , ? = 9.00 m/s2 , and ? = 1.40 m/s3 . at t = 0 the rocket is at the origin and has velocity ~v0 = v0x ? i + v0y ? j with v0x = 1.00 m/s and v0y = 7.00 m/s. (a) calculate the velocity and position vectors as functions of time. (b) what is the maximum height reached by the rocket? (c) sketch the path of the rocket. (d) what is the horizontal displacement of the rocket when it returns to y = 0?
