ebo throws a ball in the air it's velocity at the start is 18m/s at an angle of 37° to the ground express the initial velocity in component vector form?
Answered by Henry
Vo = 18m/s[37o].
Xo = 18*Cos37 = m/s.
Yo = 18*sin37 = m/s.

Ebo throws a ball into the air. Its velocity at the start is 18 m/s at
an angle of 37° to the ground.
a) Express the initial velocity in component vector form.
b) Work out the velocity of the ball as it lands. Give your
answer in component vector form.
c) Work out the range of the ball.

Answered by Soleyana
Given: U = 18 m/s
angle= 37°
a. Ux=U cos37= 18 m/s cos37°
Uy = U sin37 = 18 m/s sin37°
b. Vx = Ux = 18 m/s cos 37°
Vy = -Uy = - 18 m/s sin 37°
c. R= U^2 sin 2theta/g
R=(18 m/s)^2 × sin
2(37°)/10 m/s^2
R= 31.145 m
d. As the boy throws the ball from his hand it has an external force. ( I.e , inertial frame of reference.)
