Question

3. You are walking at a 1m/s velocity and carrying a tray with a ball at rest on the tray. You come to a brief stop and the ball rolls off the tray. What causes the ball to roll off the tray?

Help ????????????????

Answer 1

Inertia.

Step-by-step explanation:

You are moving with a speed of 1 m/s. You are carrying a tray and the ball is at rest in the tray. You stops and the ball rolls off the tray. Whenever you starts moving with a speed of 1 m/s and when ball is at rest, due to inertia of motion the ball comes in motion. But when you stops, the ball is still in motion due to its inertia.

Hence, due to inertia the ball roll off the tray.
