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.(adsbygoogle = window.adsbygoogle || []).push({});

--------------------------------------------------------------------------------

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,
