What type of power generation we should use in Ontario

An object with a mass of 7.8 kg is pulled on a horizontal surface by a horizontal pull of 50 N to the right. The friction force on this object is 30 N to the left. What is the acceleration of the object? 0.16 m/s^2 10 m/s^2 2.6 m/s^2 6.4 m/s^2

How many minutes does it take to drive 1 mile

A boy inline-skates over smooth pavement at a velocity of 6.2 m/s south. The path turns to rough asphalt, so the boy slows down with an acceleration of 1.3 m/s2 north. If his velocity on the asphalt is now 4.
