Question

Candace threw a 0.09 kg ball at an angle such that the downwards initial velocity is 15.00 m/s and the horizontal initial velocity is 18.00 m/s. What is in m/s the vertical component of the velocity of the ball 0.20 seconds after she threw it? (Do not include units in your answer and use 10.0 m/s2 for g)

Answer 1

-15.00 m/s= Voy- 1/2(10.0 m/s) (.20 sec)^2
Voy = initial velocity and is equal to 0
