Question

A ball is kicked at an angle of 30° with a speed of 10 m/s. What are its initial x and y velocities?

a) Initial x velocity = 5 m/s, Initial y velocity = 5√3 m/s
b) Initial x velocity = 5√3 m/s, Initial y velocity = 5 m/s
c) Initial x velocity = 10 m/s, Initial y velocity = 0 m/s
d) Initial x velocity = 0 m/s, Initial y velocity = 10 m/s

Answer 1

To find the initial x and y velocities of the ball, we can use the equations v*cos(theta) and v*sin(theta), where v is the speed and theta is the launch angle. In this case, the initial x velocity is 5 m/s and the initial y velocity is 5√3 m/s.

Step-by-step explanation:

To find the initial x and y velocities, we can use the following equations:

• The initial x velocity will be v*cos(theta), where v is the speed and theta is the launch angle.
• The initial y velocity will be v*sin(theta), where v is the speed and theta is the launch angle.

In this case, the speed is 10 m/s and the launch angle is 30 degrees. So, the initial x velocity is 10*cos(30) = 5 m/s and the initial y velocity is 10*sin(30) = 5√3 m/s.
