A 1000 kg car moving at 8 m/s takes a 90 degree turn (1/4 of a circle) with a radius of 30 m in 2.4 seconds. Calculate the angular velocity, centripetal acceleration, and centripetal force for the car.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

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

step-by-step explanation:

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
