8. At what point in the projectile's trajectory is the velocity vector entirely horizontal (i.e., the
vertical component of velocity is zero)?
using the Single Step button
If necessary, slow the simulation down
9. TRUE or FALSE: The acceleration of projectile is 0 m/s at the peak of the trajectory. How
do you justify your answer?
10. Pick a launch speed and angle and compare the time required for the projectile to rise to the
peak of its trajectory to the time for the projectile to fall from the peak of its trajectory.
The Single Step button and the Vector display can be used to assist in your measurements.
Repeat for other launch angles if necessary. Describe your findings.

Expert Solution
Step 1

7.

1. Trajectory equation:

y=tanθ·x-g2u2cos2θ·x2

It depends on θif angle is small, path is less steeper.

Yes angle affects path or trajectory of projectile.

 

2. Horizontal velocity:

vx=ucosθ

It also depends on angle so it is affected by angle.

But horizontal velocity is constant as gravity only affects vertical velocity.
