Jessica attains a height of 4.7 feet above the launch and landing ramps after 1 second. Her initial velocity is 25 feet per second. Find the angle of her launch.
a. Which equation can you use with the given information to solve for theta ? b. Substitute the known values and solve for theta.
What is Jessica’s height above the launch and landing ramps after 0.5 second?
What distance has Jessica traveled after 1 second?

  1. I just love how Sal Khan explains things.
    Here he does a variation of your problem, in his we are given the angle, and
    he has to find the vertical.
    In yours the vertical is given, and you have to find the angle.
