A section of a rollercoaster track involves an arc, as shown below: If the fastest the carriage can traverse this section of the track without its wheels losing contact is 8.50m⋅s−1, what is its radius of curvature? Give your answer in meters to three significant figures, without including a unit.

Natural forces that can alter ecosystems include seasons and climate changes. t or f

The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.

Asystematic approach to problem solving is called a (an)
