Question

A meteoroid changed velocity from 10 km/hr to 18 km/hr in 4 hours. What is the acceleration of the meteoroid?​

Answer 1

Answer:

The meteoroid accelerated at 26.7 meters per second per second.

Explanation:

To calculate acceleration, we use this formula:

a = vf - vi / Δt

where a = acceleration, vf = ending velocity, vi = beginning velocity, and Δt = change in time.

So:

a = 1.8 km/sec - 1.0 km/sec / 0.03 sec

a = 0.8 km/sec / 0.03 sec

a = 26.7 km/sec2
