Answer:

Student A is correct

Explanation:

This is because by student A's recording, we get the average speed = total distance/total time = 6 m/2 s = 3 m/s. Student B recorded an average speed of 1.5 m/s². This cannot be correct because it is in the unit of acceleration.

If an object with a mass of 248kg is lifted 76 meters in 18 seconds, how much power is used?
Jlenok [28]

Explanation:

power = 1/2 mass × velocity^2 >>1

velocity = distance / time = 76 /18 = 4.2m

then power = 1/2 × 276 × (4.2)^2 = 138 × 17.64 = 2,434.3 jules.
