(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:
We apply an electric field in the negative y direction
Explanation:
Since A uniform magnetic field is in the positive z direction and A positively charged particle is moving in the positive x direction through the field, the magnetic force acting on the positively charged particle is in the positive y direction according to Fleming's right-hand rule.
For the net force on the particle to be zero, we apply an electric field in the negative y direction to create an electric force on the positively charged particle, so as to cancel out the magnetic force.
Answer:
The answer is 24cm
Explanation:
This problem bothers on the curved mirrors, a concave type
Given data
Object height h= 5cm
Object distance = 12cm
Focal length f=24cm
Let the image distance be v=?
Applying the formula we have
1/v +1/u= 1/f
Substituting our given data
1/v+1/12=1/24
1/v=1/24-1/12
1/v=1-2/24
1/v=-1/24
v= - 24cm
This implies that the image is on the same side as the object and it is real
Jupiter. It states that the stronger the magnetic field, the larger the magnetosphere. Some 20,000 times stronger than Earth's magnetic field, Jupiter's magnetic field creates a magnetosphere so large it begins to avert the solar wind almost 3 million kilometers before it reaches Jupiter.
Answer:
A
Explanation:
The most important part about this is not only that objects pull on each other, but that two objects attract each other with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them. This is known as Newton's law of universal gravitation.
