A 111 kg111 kg horizontal platform is a uniform disk of radius 1.97 m1.97 m and can rotate about the vertical axis through its center. A 68.7 kg68.7 kg person stands on the platform at a distance of 1.11 m1.11 m from the center, and a 25.3 kg25.3 kg dog sits on the platform near the person 1.41 m1.41 m from the center. Find the moment of inertia of this system, consisting of the platform and its population, with respect to the axis.

Adelivery truck leaves a warehouse and travels 2.60 km north. the truck makes a left turn and travels 1.25 km west before making another right turn to travel 1.40 km north to arrive at its destination. what is the magnitude and direction of the truck's displacement from the warehouse?

The metric unit of electrical power is the watt volt ampere ohm

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
