With a quick flick of her wrist, an ultimate frisbee player can give a frisbee an angular velocity of 4.00 revolutions per second. to do this, the player accelerates the frisbee from rest through an angle of 55.0° before letting it go. (a) what is the frisbee's angular velocity, in units of rad/s, when the ultimate frisbee player releases the frisbee? rad/s (b) through what angle, in radians, does the player rotate the frisbee? rad (c) what is the frisbee's angular acceleration while the frisbee player is flicking her wrist? assume the angular acceleration is constant. rad/s2 (d) how much time does this process take?

a) w = 25.1 rad/s, b) θ  = 0.9599 rad , c) α = 328.1 rad/s²  d) t=  0.0765 s

Explanation: Let's work on this exercise with the equations of angular kinematics

a) The angular velocity is

    w = 4.00 rev / s (2π rad / 1 rev)  

     w = 25.1 rad/s

b) let's reduce the angle of degrees to radians

    θ = 55 ° (π rad / 180 °)

    θ  = 0.9599 rad

c) Let's use the initial angular velocity as the system part of the rest is zero

    w² = w₀² + 2 α θ

    α = w² / 2 θ

   α = 25.1²/2 0.9599

   α = 328.1 rad / s²

d)

   w = w₀ + α t

    t = w / α

    t = 25.1 / 328.1

    t=  0.0765 s

i think if it were me i whould divide 300 dide 15

step-by-step explanation:

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
