Answer:
The horizontal component of the 70 N force = 35·√3 N
The vertical component of the 70 N force = 35 N
Explanation:
The magnitude of the given force, F = 70 N
The angle of inclination of the given force to the horizontal, θ = 30°
By the resolution of forces, we can resolve the given force, F, into its horizontal component, Fₓ, and vertical components, , as follows;
The horizontal component of the given force = Fₓ = F × cos(θ)
Substituting the values, we have;
The horizontal component of the 70 N force, Fₓ = 70 × cos(30°) = 35·√3 N
The vertical component of the given force = = F × sin(θ)
Substituting the values, we have;
The vertical component of the 70 N force, = 70 × sin(30°) = 35 N.
The ball will be 49.5m from the base when it hits the ground based on 9.8m/s² earth gravity.
what is earth gravity?
Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.
Why do things fall down when you throw them or drop them? The answer is because gravity ; an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall.
First, let's try to find the time taken by ball to reach the ground :
t =
t =
t = 9.9 s (rounded)
Next, we will find the horizontal distance covered by ball :
D = v*t
D = 5 * 9.9
D = 49.5m
Therefore, the ball will be 49.5m from the base when it hits the ground for the first time based on 9.8m/s² earth gravity.
