Concept Check: 1. An object has a mass of 20 kg and accelerates at 15 m/s/s. What is the force applied on the object? 2. An object's mass is 20 kg, moved at 15 m/s/s. Find how much force is applied to it. 3. An object with a mass of 5 kg experiences a force of 10N. What is the acceleration of the object? 4. An object with a force of 15N on it is accelerating at 10 m/s2. What is the mass of the object?
answer 1) answer:300Newton's example:f=ma f=(20kg)(15m/s2) f=300kg m/s2 or 300N
2)answer:f300kg,m/s2 or 300J example:f=am f=(15m/s2)(20kg) f=300kg,m/s2
