A flowerpot falls off a second story windowsill and hits the sidewalk 1.5 s later with a velocity of 14.7 m/s find the average acceleration of the flowerpot

The average acceleration of the flowerpot will be .

Explanation:

The average acceleration is equal to change in velocity divided by change in time in given interval.

Here v is the final velocity and u is the initial velocity.

Given v = 14.7 m/s, u = 0 (as flowerpot falls off a second story windowsill) and .

Substitute the given values, we get

Thus, the average acceleration of the flowerpot will be .

conservation of mass

mass before something happens = mass afterwards
