... 1. What acceleration will result when a 12 N net force applied to a 3 kg object? 12 N = 3 kg x 4 m/s/s 2. A net force of 16 N causes a mass to accelerate at a rate of 5 m/s2. Determine the mass. 16 N = 3.2 kg x 5 m/s/s 3. How much force is needed to accelerate a 66 kg skier 1 m/sec/sec? 66 kg-m/sec/ ...

... • In the absence of air resistance, all objects accelerate towards Earth at the same rate. • We call this “free-fall” acceleration- meaning gravity is the only force acting on an object. • Because we use this value so often we’ll give it a name- g • What do you think g depends on? ...

... Start with a free body diagram. On the problem below, in the x direction you have simply the x components of the tension in each string. -T1x + T2x = 0 or T2x = T1x since the x component of T1 is in the negative direction, this will work out. T1x = T1cos(70) and T2x = T2 cos(50) In the y direction t ...
