Unformatted text preview: down the plane. a s = g Sin q Example of forumula: A skiers speed at the bottom of a 100 m slope is 20 m/s. What is the angle of the slope? v 2s 2 = v 1s 2 +2 a s Dx = 2 g Sin q Dx, so Sin q = v 2s 2 /(2 g Dx) = (20 m/s) 2 /[2(9.80 m/s 2 )(100 m)] = 0.204 q = Sin1 (0.204) = 11.8 O VECTORS Forces A= F/m The force is directly proportional while the mass is inversely proportional M is always positive. W=mg Where W is weight, m is mass and g is gravitational force of 9.8m/s 2...
