1. What force is needed to accelerate a 5 kg bike at 9 m/s^2.

2. What is the acceleration of a 3 kg object that has a net force of 10 N on it?

3. An elevator is being accelerated upward. What force of tension is needed to accelerate a 27 kg elevator at 9 m/s^2

4. An elevator is accelerating downwards as a person needs to go from the 10th floor to the 2nd floor. What force of tension is needed to accelerate a 28 kg elevator at -2 m/s^2 5. A 2 kg box is pushed with a force of 36 N on a concrete floor and is accelerating to the right at 3 m/s^2. What is the force of friction acting on the box? (Note, friction is acting to the left so your answer should be negative!)

6. A 5 kg box is pushed with a force of 29 N on a concrete floor and is accelerating to the right at 2 m/s^2. What is the coefficient of friction between the ground and the box? (Hint - find the force of friction acting on the box just like question 5, then use the friction equation to solve!) (round to the hundreds place 0.00)
