1. A force F applied to an object of mass m1 produces an acceleration of 3.00 m/s2. The same force applied to a second object of mass m2 produces an acceleration of 1.10 m/s2.
(a) What is the value of the ratio m1/m2?
????
(b) If m1 and m2 are combined, find their acceleration under the action of the force F.
???? m/s2
2. A 3.15 kg object is moving in a plane, with its x and y coordinates given by x = 3t2 - 4 and y = 3t3 + 5, where x and y are in meters and t is in seconds. Find the magnitude of the net force acting on this object at t = 1.95 s.
