What is the magnitude of the net force which acts on the object?
What is the magnitude of the net force when the object encounters 23.4 N of air resistance?
What is the magnitude of the net force when it falls fast enough to encounter an air resistance of 50.5 N?
A 6 kg object undergoes an acceleration of 2.2 m/s2. What is the magnitude of the resultant force acting on it?
If this same force is applied to a 4.9 kg object, what acceleration is produced?
A 3.7 g bullet leaves the muzzle of a rifle with a speed of 348 m/s. What total constant force is exerted on the bullet while it is traveling down the 0.8 m long barrel of the rifle?
A boat moves through the water with two forces acting on it. One is a 2458 N forward push by the motor on the propeller, and the other is an 2187 N resistive force due to the water around the bow. What is the acceleration of the 1325 kg boat?
If it starts from rest, how far will it move in 15.4 s?
What will its velocity be at the end of this time interval?
A 6.3 kg bucket of water is raised from a well by a rope. The acceleration of gravity is 9.8 m/s2.
If the upward acceleration of the bucket is 5.5 m/s2, find the force exerted by the rope on the bucket.
