KILOGRAM definition and meaning | Collins English Dictionary

97 kg

A body of mass 7 kg is projected vertically upward with an initial velocity of 11 meters per second. The gravitational constant is g = 9.8 m/s^2. The air resistance is equal to k|v|, where k is a constant. Find a formula for the velocity at any time (in terms of k):v(t) =

SOLVED: A uniform solid disk with a radius of 7 cm has a mass of 0.5 kg (moment of inertia I = (1/2)MR^2). A constant force of 12 N is applied as shown. At the instant shown, the amount of string that has wound off the disk is d = 40 cm, and the angular velocity of the disk is 35 radians/s into the page.(b) At a time 0.2 s later, what are the magnitude and direction of the angular momentum about the center of the disk?(c) At this later time, what are the magnitude and direction of the angular ve
