Answer:
v₀ = 16.55 m/s
Explanation:
This motion of the ball can be modeled as a projectile motion with following data:
R = Range of Projectile = 27.5 m
θ = Launch Angle = 50°
g = acceleration due to gravity = 9.81 m/s²
v₀ = Initial Speed of Ball = ?
Therefore, using formula for range of projectile, we have:
<u>v₀ = 16.55 m/s</u>

Answer:
The Moon revolves or moves around the Earth in a path called its orbit and rotates, or spins, in space.
Explanation: The Moon's movements cause the phases of the Moon and the Earth's ocean tides.
Unicellular: An organism that consists of a single cell

Asexual reproduction: When an organism has the ability to create offspring without the help of another organism
Sexual Reproduction: When two organisms create an offspring using the gametes
Work = force in the direction of the movement x distance = 27 N x 1.7 m
Work = 45.9 joules
