1. If the incline plane were to suddenly disappear, then what would the acceleration be on the ball in the the y-direction if the angle of an the inclined plane is 24o ? (Unit will be in m/s^2, which is the same is m/s2) 2. What is the acceleration if change in velocity is 4.49 m/s and the time interval of this change in velocity is 4.16 s? (Your answer will be in m/s^2) 3.What is the velocity of a car that has an acceleration of 1.96 m/s2 in a time interval of 1.42 s? (Units will be in m/s) 4. What is the distance an object travels that is experiencing an acceleration of 4.22 m/s2 for a time interval 8.78 s? (Distance will be in m) 5. What is the velocity of and object that falls with an acceleration of 7.01 m/s2 in a time of 5.02 s? (The acceleration is less than 9.81 m/s2 because there is an air resistance acting on the object.) 6.What is the acceleration for an object that has a mass of 6.53 kg which experiences a force of 2.89 N? 7. How far will an object fall in a time 2.19 s ? (We will use g = 9.81 m/s2 for the acceleration on an object near the surface of the earth) 8.What is the speed of and object that has a force acting on it which produces an acceleration of 7.22 m/s2 for a time of 1.21 s? (Units for speed is m/s)  9. What is the acceleration for an object that has a mass of 9.28 kg which experiences a force of 7.12 N?  10.  The way that we quantify inertia is with mass. If an object consists of two different kinds of masses, one mass is 9.06 and the other mass is 7.92, then what is the total mass of the object? (The unit for mass is in kg.) 11. The mass of a cylinder is 9.01 kg what is the mass of the cylinder? 12. What is the acceleration for an object that has a mass of 6.84 kg which experiences a force of 5.39 N? 13.What is the acceleration for an object that has a mass of 7.04 kg which experiences a force of 4.66 N?  14.What is the acceleration for an object that has a mass of 6.59 kg which experiences a force of 3.88 N?  15.What is the acceleration for an object that has a mass of 9.14 kg which experiences a force of 5.57 N?  16. What is the acceleration for an object that has a mass of 2.35 kg which experiences a force of 4.05 N? 17. What is the acceleration of an object that has a change in velocity of 2.92 m/s in a time interval of 7.58 s? (Units for acceleration are m/s^2) 18.What is the average speed of an object that travels a total distance of 8.75 m in a time interval of 9.35 s? (Please put your answer in with two decimal places) 19. What is the velocity of a freely falling object in a time of 2.08 s? (Velocity is in units of m/s and g will be 10 m/s2? 20. What is the velocity of a car that has an x-displacement of 3.7 m in a time interval of 4 s?
