A Child Kicks a Ball: Horizontal Component of Initial Velocity Calculation

What is the horizontal component of the ball's initial velocity when kicked at an angle of 35 degrees with an initial speed of 8.5 meters per second?

The horizontal component of a ball's initial velocity, kicked at an initial speed of 8.5 m/s at an angle of 35 degrees, can be calculated using the formula Ux = U cosine θ. The result is approximately 6.96 m/s.

Understanding Projectile Motion

When a ball is kicked at an angle with an initial velocity, it follows a curved path known as projectile motion. This concept is an essential part of Physics, involving the analysis of objects in motion under the influence of gravity.

Calculating the Horizontal Component

To determine the horizontal component of the ball's initial velocity, we use the formula: Ux = U cosine θ In this scenario, the initial velocity (U) is 8.5 m/s and the angle (θ) is 35 degrees. By substituting these values into the formula, we can compute the horizontal component as follows: Ux = 8.5 m/s * cos(35) = 6.96 m/s (approximately) Therefore, the horizontal component of the ball's initial velocity when kicked at an angle of 35 degrees with an initial speed of 8.5 meters per second is approximately 6.96 m/s. This value represents the speed at which the ball moves horizontally throughout its trajectory.
