So first make a force diagram. I would label forward forces + and backward forces -. Essentially, the drag force is equal to the Ft (force of tension) + Ff (force of friction on snowmobile - driver system). The force of Friction is equal to mu * Fn. We can find mu through the force of friction acting on the sled. 120 N = mu * Fn (equal to m * g of sled). mu of the Ice is equal to 0.167. So, 540 N = Ft + 0.167 * 4500 N. Ft = -211.5 N. <u>Ft is acting in the backwards direction at a magnitude of 211.5 N</u>
Answer:
Reaction force = Weight
the force exerted by A on B is equal.
M1a = M2a
Explanation: I think the answer is right if wrong message me.
<span>Nodes are points along the medium that appear to be standing still. They are points on a standing wave that has no displacement from the rest position.
Antinodes are the opposite of nodes. Those are</span> points that undergo the maximum displacement.
<span>At the nodes the destructive interference occurs</span> . For example <span>a crest of one wave meets a trough of a second wave</span> , or a half-crest of one wave meets a half-trough of a second wave...
The two types of mechanical waves are longitudinal waves, and transversal waves.
