Gravity acts equally on objects regardless of mass. The student launches a tennis ball of the same size but with twice the mass of the first ball tested. He uses a launch angle of and a launch velocity of 15 m/s. What is the best estimate of the distance the ball will travel?

Questions below are based on the following passage: To launch tennis balls from varying angles and at different speeds, a student builds the catapult shown in Figure 1. The tennis ball is propelled out of the catapult with velocity and angle  .  The student conducts two experiments to measure the distance between the launch site and where the ball lands. The student varies, launches the ball at a constant 15 m/s, and measures the distance travelled. The results are provided in Figure 2.  In the second experiment, the student varies the launch velocity of the ball, launches it at a... Show more

Questions below are based on the following passage:

To launch tennis balls from varying angles and at different speeds, a student builds the catapult shown in Figure 1. The tennis ball is propelled out of the catapult with velocity and angle  . 

The student conducts two experiments to measure the distance between the launch site and where the ball lands.

The student varies, launches the ball at a constant 15 m/s, and measures the distance travelled. The results are provided in Figure 2. 

In the second experiment, the student varies the launch velocity of the ball, launches it at a constant  angle, and measures the distance travelled. The measurements are recorded in Figure 3.
