Question

Please answer all parts this is my last question.

An athlete approaches the bar in a running broad jump competition with a
velocity of 7.85 m/s. The displacement (c) of the center of gravity from a
crouched to the take-off position is 55 cm.
A. What is the magnitude of the vertical component of launching velocity
(m/s)?
B. What is the magnitude of the launching velocity (m/s)?
C. What is the angle of the launching velocity (in degrees) relative to the
horizontal?
D. What is the range (meters)?
Note: Round off your entries up to 3 decimal places; for quantities less
than 0.01 use up to 3 significant digits.
