Physics Help please.....?
1. A slingshot is fired at an angle of 22 degrees w/ an initial velocity of 100m/s. What horizontal distance will it travel?
2. Ringo is going to jump off of a high dive that is 61m high. There is a timy pool 23m out from the tower; w/ what horizonal velocity must he jump in order to avoid his demise?
WORK PLEASE
1. use the equation x = Vx*t to find the horizontal distance.
Vx= Vocos(theta), so in this case, Vx=100cos22. To find t, use the equation y = Vyo*t - (1/2)gt^2. Change in vertical height (y) will be zero, g is the gravitational constant 9.81 m/s2, and Vyo= Vosin(theta).
Using this quadratic, solve for t. Then plug it into the initial equation so solve for x
2. This problem is similar, except you are given x = 23m. Solve for t using y = Vyo*t - (1/2) gt^2, given that y = 61m and Vyo is zero.
