Consider two projectiles that can be shot upward by spring guns. Object A is made of solid aluminum and has a mass of 50 grams. Object B is made of cast iron and has a mass of 200 grams. For this problem, you may take the gravitational field strength to be g = 10 N/kg.
i. Masses A and B are both shot straight upward at the same time. Mass A is shot with a speed of 2 m/s and mass B with a speed of 1 m/s. Which one hits the ground first? They will hit the ground at the same time. Object A It is impossible to determine this. Object B
ii) Explain your reasoning in part i
iii) Find an equation that express how high a ball rises, if it is shot straight up with a speed v0, it has a mass m, and the gravitational field strength is g. Solve h= in terms of g, m, and v0
iv) Both masses are shot upward with a velocity of 2.0 m/s. How high does object A go in meters? (Ignore air resistance.) ha= in meters
v) Both masses are shot upward with a velocity of 2.0 m/s. How high does object B go in meters? (Ignore air resistance.) hA= meters
vi) Masses A and B are both shot straight upward at the same time. Mass A is shot with a speed of 2 m/s and mass B with a speed of 1 m/s. Which one hits the ground first?
vii) Name three physical quantities you could calculate based on this information.

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
