Question
Transcribed Image Text:A projectile with mass 7 kg is fired from a catapult at an enemy's castle. The position of the projectile's location is recorded at six different times. All distances have been measured in meters.
1 =< 60, 176.5, 0> m at t = 1s,
2 = 100, 199,0 > m at t = 2s,
3 =
180, 163,0> m at t = 4s,
4 =
260, 19,0> mat t = 6s,
5 = 340, -233,0> mat t = 8s,
6 =< 380,-399.5, 0> m at t = 9s.
(a) Calculate the average velocity at positions 1, 2, and 3.
At position 1: < 60
At position 2: < 40
At position 3: < 40
