Question 1 A monkey pushes a 17kg go-kart with a force of 260 N. No other force affects motion. What is the acceleration of the cart?
Q2 A 27 kg ball in free fall on earth? What is net force? What is the acceleration? What would be the acceleration of the ball if at a point of time during the fall, there is 20 N of air resistance applied to it?
Q3 A 27 kg ball rolling on level smooth ground, being pushed by a 5 N force. What does the word smooth indicate? Draw a F.B.D, and determine the value of all forces on ball. What is the net force on ball? What is the acceleration of object?
Q4 Rolling a 27 kg ball on a rough level surface that generates a constant 3 N of friction. The forward push of the ball is 5N. What is the net force? What is the acceleration?
Q5 A 2789 kg helicopter accelerates upward at 2.5 m/s2. What is the lift force exerted by the air on the propellers? What would be the new lift force on the helicopter if a 500 kg jeep was attached to it and it still accelerates upward at 2.5 m/s2?
Q6 A 4500kg car moves down a level highway at 20 m/s. If 1300 N of force pushes it forward and a 650 N resistance (friction and air resistance combined) pushes backward on object, find the following… The acceleration of object How fast object travels after 1 minute How far it travels after 1 minute.
Q7 Nicole slows down in her BMW from 15 m/s to 3 m/s in 42 seconds. What is the mass of her car if the net force on it is 7312 N?
