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 7.21 m/s at an angle of 32.9° 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.

A golf ball is hit off a tee with an initial velocity of 42.9 m/s at an angle of 34.5 degrees above the horizontal. Assume the golf ball moves through the air as a projectile and use your projectile equations to answer the following questions. (Once you have become successful on this question, use the strategy on other questions.)

  1. What is the horizontal component of the initial velocity?

    Horizontal component
