  1. y0 = 0 m a = +9.8 m/s2 Free fall acceleration is always down, if down is positive then so is acceleration, if up is positive, then acceleration is negative +y Find v and y at t = 1 s v0 = 0 m/s V= 9.8 m/s 5 m 10 m Coyote was not going 9.8 m/s during the entire first second, use average velocity 15 m 20 m 25 m 30 m 35 m 40 m 45 m

  2. y0 = 0 m a = 9.8 m/s2 Find v and y at t = 2 s v0 = 0 m/s +y V= 9.8 m/s 5 m 10 m 15 m V= 19.6 m/s 20 m 25 m 30 m Or: 35 m 40 m 45 m

  3. y0 = 0 m a = 9.8 m/s2 Find v and y at t = 3 s v0 = 0 m/s +y V= 9.8 m/s 5 m 10 m 15 m V= 19.6 m/s 20 m 25 m HELP! 30 m Or: 35 m 40 m V= 29.4 m/s = 66 mph! 45 m

  4. y0 = 0 m a = 9.8 m/s2 v0 = 0 m/s +y V= 9.8 m/s 5 m Can you find v and y at t = 4 s ? No Peeking, solve it yourself first! 10 m v = 39.2 m/s, y = 78.4 m 15 m Can you find t and y when v = 25 m/s? No Peeking, solve it yourself first! V= 19.6 m/s t = 2.55 s, y = 31.9 m 20 m Can you find t and v when y = 10 m? 25 m No Peeking, solve it yourself first! t = 1.43 s, v = 14 m/s 30 m Nice Job, take a break. 35 m 40 m V= 29.4 m/s 45 m
