A student fires a cannonball diagonally at an angle of 71° with an initial speed of 31m/s. Neglect drag and the initial height of the cannonball.

What was the cannonball's initial horizontal speed?

What was the cannonball's initial vertical speed?

How long did the cannonball rise?

What was the cannonball's total flight time?

What was the cannonball's maximum height?

How far from the cannon did the cannonball land (measured along the ground)?

vx = 10.09 m/s

vy = 29.31 m/s

t = 5.98 s

ymax = 43.83 m

xmax = 60.37 m

Explanation:

A) The horizontal speed is constant in the complete trajectory. It is given by:

B) The vertical initial speed is:

C) The flight time is given by:

D) The maximum height is:

E) The maximum horizontal distance is:

answer and explanation;

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
