Answer:
15.77m/s
Step-by-step explanation:
the information we have is:
initial velocity

distance:

angle:
°
first we need to break down the velocity into its x and y components:
initial velocity in x (the velocity in x is constant):

and initial velocity in y (the velocity in y is not constant due to acceleration of gravity):

and now we find the time that the ball was in the air:

and with this time, we find the y component of the volicity at time 1.96s:
(negative because it points downward)
finally, to find the final velocity we use pythagoras:
