A hockey puck with mass 0.19 kg is stationary on the ice. A hockey player uses her stick to shoot the puck by applying a 6.0 N force over a distance of 1.4 m. What is the change in the velocity of the puck? Group of answer choices

0.045 m/s

0.80 m/s

0.89 m/s

44 m/s

9.4 m/s

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied. true or false

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.)

Acar moves a distance of 50.0 km west, followed by a distance of 64.9 km north what was the magnitude of the displacement of the car, in units of kilometers?
