Analysing Projectile Motion – Practice
Questions:
1) A 150kg package is dropped from an army plane and accelerates toward the Earth.
a) What is the acceleration of the package if we assume a constant drag force of 195N?
b) What is the packages vertical speed 7 seconds after jumping out of the plane?
2) A projectile is launched with an initial velocity of 100 m/s at an angle of 15° to the horizontal as shown below. Calculate the horizontal and vertical components of the projectiles velocity:
3) A projectile is launched with an initial velocity of 40 m/s at an angle of 70° to the horizontal. Calculate the horizontal and vertical components of the projectiles velocity:
Quick Answers:
1a) 8.5 m/s2 b) 59.5 m/s
2) Horizontal = 96.6 m/s Vertical = 25.9 m/s
3) Horizontal = 13.7 m/s Vertical = 37.6 m/s
