A tennis ball is thrown upwards from the edge of a cliff with a speed of 10 -. It lands on the ground below the S cliff 3.0 seconds later. We can ignore air resistance. What is the displacement of the tennis ball?

30 m North

Explanation:

Displacement is defined as the distance moved, in a specified direction. Basically, the difference between distance and displacement is that displacement always has the direction in which the force is moving attached. That being said,

Speed = distance moved/time taken, making distance subject of formula, we get

Distance moved = speed * time taken.

Thus, distance = 10 * 3., I'm guessing the speed is in m/s unit, since you didn't state, otherwise, you convert it from whatever it is in, into m/s multiply by the time taken.

Distance = 30 m.

The displacement I reckon would be 30 m North.

answer; i believe the correct answer is (40,000 j) good luck

attach the statements so i can answer : )
