Question

Barker is unloading 20kg bottles of water from this delivery truck when one of the bottles tips over and slides down the truck ramp that is inclined at an angle of 30 degrees to the ground. what amount of force moves the bottle down the ramp?

Answer 1

The overall force that is acting on the bottle is gravity. With the incline being 30 degrees the full force of gravity isn't acting on the bottle becuase the ramp isn't allowing the bottle to go straight down. By taking the sin of 30 degrees you find the proportion of gravity that is acting on the bottle to be 4.9 meters per second and the bottle weights 20 kg so the force acting on the bottle is 98 Newtons.
