When a ball is dropped out of a window it hits the ground at a speed of 12 m/s. If the ball were thrown horizontally out of the same window at a speed of 5 m/s, then what would be its speed when it hits the ground? (a) 0 m/s (b) 5 m/s (c) 7 m/s (d) 12 m/s (e) 13 m/s (f) 17 m/s (g) none of the above

Acurve connects the data points that are plotted. (physical science chapter 11 motion)

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) sketch the trajectory using an appropriate coordination system. b) how long for the projectile to reach the ground. c) how far did projectile travel horizontally before striking the ground. d) determine the projectilex & y position at t-1.3s e) determine the magnitude and direction of projectile velocity at t= 1.3s f) determine the magnitude and direction of projectile acceleration at t-1.3s
