A net force of 51 N pushes a 24 kg lawn mower. Its acceleration is about:
A4.2 m/s squared
B51 m/s squared
C2.1 m/s squared
D0.5 m/s squared
Answer & Solution
Correct answer: C. 2.1 m/s squared
1. Acceleration equals net force over mass.
2. 51 divided by 24 gives about 2.1.
3. The direction matches the net force.
