Use your data (attachment) from Part 3 and Newton’s laws to explain why the force meter measures a force if the cart is moving a
t a constant velocity. You should cover the following points. State Newton’s first law.
• Identify the forces acting on the cart.
• Describe the relationships between applied force and mass and between applied force and weight as linear (from data or mathematical derivation by applying Newton’s first law).
• Explain why the data are linear in terms of Newton’s first law.
• Graph F versus mass + cart.

Answer:
32.46m/s
Explanation:
Hello,
To solve this exercise we must be clear that the ball moves with constant acceleration with the value of gravity = 9.81m / S ^ 2
A body that moves with constant acceleration means that it moves in "a uniformly accelerated motion", which means that if the velocity is plotted with respect to time we will find a line and its slope will be the value of the acceleration, it determines how much it changes the speed with respect to time.
When performing a mathematical demonstration, it is found that the equations that define this movement are the follow
Where
Vf = final speed
Vo = Initial speed =7.3m/S
A = g=acceleration =9.81m/s^2
X = displacement =51m}
solving for Vf
the speed with the ball hits the ground is 32.46m/s
