(1) The vertical magnitude of the ball's initial velocity is 16.075 m/s,
(2) The maximum height of the ball is 13.18 m
(1) To Calculate the vertical component of the ball's initial velocity, we use the formula below.
Formula:
- Vy = Vsin∅........................ Equation 1
Where:
- Vy = vertical component of the ball's initial velocity
- V = Initial velocity of the ball
- ∅ = angle to the horizontal.
From the question,
Given:
Substitute these values into equation 1
- Vy = 25(sin40°)
- Vy = 25×0.643
- Vy = 16.075 m/s.
(2) To calculate the maximum height reached by the ball, we use the formula below.
Formula:
- H = (Vy)²/2g............... Equation 2
Where:
- g = Acceleration due to gravity = 9.8 m/s²
Substitute the value above into equation 2
- H = (16.075)²/(2×9.8)
- H = 13.18 m
Hence, (1) The vertical magnitude of the ball's initial velocity is 16.075 m/s, (b) The maximum height of the ball is 13.18 m.

Answer:
Four times higher
Explanation:
F- G (m1 x m2)/ r^2
if r 1 = 2 and r 2 = 1 therefore F = G (m1 x m2)/ 1^2 is 4 times higher than
2^2 since G and m1 and m2 remained the same
