Q: If an object with a mass of 25 kg is moving with the same acceleration as 8ms⁻², then the force exerted by the object is –––––.
  • A. 200 N
  • B. 200 J
  • C. 200 ms⁻²
  • D. 200 ms⁻²
Correct Answer: Option A - Mass (m) = 25 kg Acceleration (a) = 8ms⁻² Force exerted by the object (F) = m.a = 25 × 8 = 200 N
A. Mass (m) = 25 kg Acceleration (a) = 8ms⁻² Force exerted by the object (F) = m.a = 25 × 8 = 200 N

Explanations:

Mass (m) = 25 kg Acceleration (a) = 8ms⁻² Force exerted by the object (F) = m.a = 25 × 8 = 200 N
