Question

1)At the instant traffic turns green, an automobile that has been waiting at an intersection of roads accelerats with 5ms-2. At the same instant a truck traveling with a constant velocity. (i) how far beyond its starting point will be automobile overtake the truck? (ii)how fast will it be traveling? (2) An object is projected with an initial velocity U at an angle B with a plane inclinee at an angle A with the horizontal. Derive an expression for the angle of the projectile.

Answer 1

x1 = 1/2 at^2
x2 = vt

Obviously we need the speed of the truck.
