Calculation of the Height, Distance, and Time of a Ball Thrown at an Angle

To calculate the height, distance, and time of a ball thrown at an angle of 45 degrees with a velocity of 5 m/s, we can use the equations of projectile motion.

1) Height Reached by the Ball:

The height reached by the ball can be calculated using the formula:

h = (v0^2 * sin^2(θ)) / (2 * g)

Where: - h is the height reached by the ball - v0 is the initial velocity of the ball (5 m/s) - θ is the angle at which the ball is thrown (45 degrees) - g is the acceleration due to gravity (approximately 9.8 m/s^2)

Substituting the given values into the formula, we can calculate the height:

h = (5^2 * sin^2(45)) / (2 * 9.8)

Calculating this expression gives us the height reached by the ball.

2) Distance Covered by the Ball:

The distance covered by the ball can be calculated using the formula:

d = (v0^2 * sin(2θ)) / g

Where: - d is the distance covered by the ball - v0 is the initial velocity of the ball (5 m/s) - θ is the angle at which the ball is thrown (45 degrees) - g is the acceleration due to gravity (approximately 9.8 m/s^2)

Substituting the given values into the formula, we can calculate the distance:

d = (5^2 * sin(2 * 45)) / 9.8

Calculating this expression gives us the distance covered by the ball.

3) Time of Flight of the Ball:

The time of flight of the ball can be calculated using the formula:

t = (2 * v0 * sin(θ)) / g

Where: - t is the time of flight of the ball - v0 is the initial velocity of the ball (5 m/s) - θ is the angle at which the ball is thrown (45 degrees) - g is the acceleration due to gravity (approximately 9.8 m/s^2)

Substituting the given values into the formula, we can calculate the time of flight:

t = (2 * 5 * sin(45)) / 9.8

Calculating this expression gives us the time of flight of the ball.

Please note that the above calculations assume ideal conditions and neglect air resistance.

Let's calculate the values using the given formulas.
