18 Golfer & ball A golfer hits a golf ball, imparting to it an initial speed of 53 m/s directed 27' above the horizontal. Assuming that the
mass of the ball is 41 g and the club and the ball are in contact for 1.0 ms. Find
b) the magnitude of the average force, in Newtons, exerted on the ball by the club:

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
