A truck, mass 2000 kg, is moving 20 meters per second and is acted on by two constant forces; a forward force of 800 N from the engine and a 300 N retarding force from friction of the tires on the road.
a) What is the rate of acceleration of the truck?
b) How far does it move in 10 seconds?
and the other one:
A small rocket is launched with an initial velocity of 75 meters per second at an angle of 28 degrees with the horizontal. Find the:
a) Maximum height
b) range
c) time in air
