(01.04 LC)Which of the following quantities is a vector quantity?

(02.05 MC)An object is allowed to fall freely near the surface of an unknown planet. The object falls 88 meters from rest in 5.0 seconds. The acceleration due to gravity on that planet is

(02.06 MC)Determine the reaction force for this given action force: Human pushes on a door.

(03.02 HC)The mass of a large fitness equipment box is 225 kg. The minimum horizontal force needed to get this object to move across the carpet is 1,404 N. What is the coefficient of friction between the carpet and the box, and what type of friction is this?

(02.05 LC)Finish this statement: Gravitational force causes objects to be in free fall when

(03.09 MC)A new ride being built at an amusement park includes a vertical drop of 79.8 meters. Starting from rest, the ride vertically drops that distance before the track curves forward. If friction is neglected, what would be the speed of the roller coaster at the bottom of the drop?

(02.06 MC)Determine the reaction force for this given action force: Human pulls on an animal.

(03.08 LC)Which of the following is a unit for power?

(02.07 MC)After the light turned green, a car accelerated from rest to 28.0 m/s. This happened over 4.23 seconds. If the total mass of the car is 1,876 kg, what was the magnitude of the net force to cause this acceleration?

(01.07 LC)A car travels 25.0 meters in the first 10.0 seconds of a trip and 40.0 meters in the next 10.0 seconds of the trip. What is the average speed of the car in meters per second for the total trip?
