On takeoff, the propellers on a UAV (unmanned aerial vehicle) increase their angular velocity for 3.0 s from rest at a rate of omega equals 15.8 space t space fraction numerator r a d over denominator s end fraction where t is measured in seconds. What is the instantaneous angular velocity of the propellers at 2.36 s

What determines the amount of inertia an object has

Does heating a metal wire increase or decrease its electrical resistance? why?

Asled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slidesa distance d1 down the slope and then covers the distance d2 alongthe horizontal terrain before stopping. find the coefficient ofkinetic friction μk between the sled and the ground, assumingthat it is constant throughout the trip. find the coefficient of kinetic frictionμk. express your answer in terms of someor all of the variables d1, d2, and θ.
