 1. VP11Q4
Points: 0/14

A projectile is launched from ground level with a velocity of 34.6 m/s at an angle of 60 degrees above the horizontal. The projectile is in the air for 6.0 seconds before it lands at the same height from which it was originally launched. Use your projectile motion concepts to determine the vx and vy values at 1.0-second intervals of time. The initial values are listed in the table. When entering values, use a negative sign to indicate a downward vy. Use a g value of 10.0 m/s/s.

Sharon Steady and Al Wayskachon won South’s recent egg toss contest held during Homecoming week. In their winning toss, Sharon gave the egg an underhand toss, releasing it with a velocity of 7.36 m/s at an angle of 29.7° to the horizontal. To the pleasure of the crowd, Al caught the egg at the same height as the toss without even a fracture to its shell.

  1. Calculate the horizontal component of the initial velocity.

Kimora rides horses as a hobby. While participating in a competition, she approaches a tall barrier. Kimora (and the horse) launch themselves into the air at 5.20 m/s and an angle of 19.3° above the horizontal. 

  1. Calculate the x-component of the initial velocity.
