900 m/s Solution If we calculate the time it takes the axle to rotate 20, then we can calculate the time it takes the bullet to travel the distance between the two discs. The discs rotate at 3,00 rpm which is equal to 3,000 / 60 = 50 revolutions per second 20º is 20º / 360º = 0.0556 of a complete revolution Therfore the disc rotates 20º in 0.0556 / 50 = 0.0011 s Which means the bullet travels 1 m in the same amount of time The linear velocity of the bullet is therefore 1 / 0.0011 m/s = 900 m/s.

90 m Solution First, calculate the X and Y components of the initial velocity V x = V x cos53º­ V y = V x sin 53º V x = 25 x 0.6 V y = 25 x 0. Download Timeline Template Omni Graffle Coupon on this page. 8 V x = 15 m/s V y = 20 m/s Vertical motion: Calculate the time taken for the projectile to reach its maximum height: V final = V initial – g x T 0 = 20 – 9.8 x T T = 2 s Calculate the maximum height: Y = V y x T x SIN(A) - g x T 2 / 2 H = 20– 9.8 x 2 2 / 2 H = 20 m H max – 20 + 60 = 80 m Free fall from the maximum height: H = ½ x g x T 2 80 = ½ x 9.8 x T 2 T = 4 s Therefore the total time = 4 + 2 = 6 s Horizontal motion: X = V x T = 15 x 6 X = 90 m.
