A baseball is thrown with one quarter rotation that takes 1.35 seconds. What is the angular velocity in units of radians per second?

Step-by-step explanation:

Angular speed is given by , where is angle change in radians and is elapsed time.

Since the baseball makes one fourth (one quarter) of a rotation in 1.35 seconds, it will take the baseball seconds to complete on rotation.

One rotation is 360 degrees or radians. Therefore, the angular speed of the baseball is:

3 ft

step-by-step explanation:

since the triangle is right use pythagoras' identity to solve for a

the square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

a² + 8² = ( )²

a² + 64 = 73 ( subtract 64 from both sides )

a² = 9 ( take the square root of both sides )

a = = 3

b or 2, just plug these equations into your graphing calculator then check the graph to see the image. if it matches up then that's your answer!
