Two ropes are attached to a 35 kg object. The first rope applies a force of 20 N and the second applies a force of 55 N. If the two ropes are perpendicular to each other, what is the resultant acceleration of the object?

Explanation:

Given:

forces by two mutually perpendicular ropes of the attached to the object:

Now we find the resultant force effect due to the two given forces:

Now the acceleration will be due to this resultant force:

Explanation:

mass of the object, m = 35 kg

Force in one direction, F1 = 20 N

force in perpendicular direction, F2 = 55 N

The net force is given by

F = 58.5 N

Let a be the net acceleration.

By the newton's second law

F = m a

58.5 = 35 x a

a = 1.67 m/s²

object 2 because all the other ones are wrong

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
