A ball is thrown into the air from ground level. After a time t = 1 s, the ball has traveled to a position x1 = 28 m to the right of and y1 = 13 m up from where it was thrown (at this time, the x and y components of the ball's velocity are still positive). The axes show the x and y directions to be considered positive.
--------------------------------------------------------------------------------
a) What was the x component of the initial velocity of the ball?
v0x = m/s *
--------------------------------------------------------------------------------
b) What was the y component of the initial velocity of the ball?
v0y = m/s *
15.97 NO
HELP: Look in your book for an equation.
HELP: You need an equation relating initial velocity, the change in position, acceleration, and time.
--------------------------------------------------------------------------------
c) What was the initial speed of the throw?
v0 = m/s *
HELP: Use the answers from parts (a) and (b).
--------------------------------------------------------------------------------
d) What was the initial angle of the throw relative to the horizontal? Please enter your answer in degrees.
q0 = ° *
--------------------------------------------------------------------------------
e) What is the height of the ball at the top of its path?
h = m
8.1 NO
I need help with part e, that's it
Thanks,
