A meteoroid changed velocity from 1.0 km/s to 1.8 km/s in 0.03 seconds. What is the acceleration of the meteoroid?

Answer 1

To calculate acceleration, we use this formula:

a = v_f - v_i / Δt

where a = acceleration, v_f = ending velocity, v_i = 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

The meteoroid accelerated at 26.7 meters per second per second.
