The cart of mass 10 kg shown above moves without frictional loss on a level table. A 50 N force pulls on the cart horizontally to the right. At the same time, a 30 N force at an angle of 60 above the horizontal pulls on the cart to the left. What is the magnitude of the horizontal acceleration of the cart?

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

the force on the thing and the distance the force moves the thing

be subject to a force andchange its motion
