Vo = 40m/s[30o].
Xo = 40*Cos30 = 34.64 m/s.
Yo = 40*sin30 = 20 m/s.
V = (34.64x + 20.00y)m/s.
MULTIPLE -CHOICE QUESTION
A baseball is launched from the bat at an angle
θo = 30° what respect to the positive x-axis and with an initial speed of 40 m/s ,and it is caught at the same height from which it is was hit. Assuming ideal projectile motion (positive y-axis upward) ,the velocity of the ball when it is caught is
a. (20.00x+34.64y)m/s
b. (-20.00x+34.64y)m/s
c. (34.64x-20.00y)m/s
d. (34.64x+20.00y)m/s
