An object has a uniform acceleration of +10 m/s2. By how much does the object’s velocity increase each second? By how much does the velocity increase in 2 seconds? If a net/total force of +25 Newtons is causing this acceleration, what is the mass of the object? If there are only two forces on the object, and they are pulling in opposite directions and one of the forces is +30 N, what is the second force?

Question
- An object has a uniform acceleration of +10 m/s2. By how much does the object’s velocity increase each second? By how much does the velocity increase in 2 seconds?
- If a net/total force of +25 Newtons is causing this acceleration, what is the mass of the object?
- If there are only two forces on the object, and they are pulling in opposite directions and one of the forces is +30 N, what is the second force?
- If the second force increases suddenly to – 50 N, what will the new acceleration be?
- If the object starts with a velocity of 5 m/s, is it likely to change direction eventually once the second force is applied?
