A rock tied to a string is moving at a constant speed of in a circle of radius Calculate the approximate magnitude of the centripetal acceleration of the rock.
The above picture is a
kg car passing the top of a hill with radius of curvature
m at a speed of
m/s. Find the magnitude of normal force on the car (in N).
Gravitational acceleration is m/s .
A puck of mass
slides in a circle of radius
on a frictionless table while attached to a hanging ball of mass
by a cord through a hole in the table, as shown in the figure above. Approximately how fast must the puck move in order to keep the ball at rest?
The gravitational acceleration is
A block is hung by a string from the roof of a van. The van drives along a straight, flat road at a constant speed of and the block hangs vertically down. Then the van goes around an unbanked curve of radius while maintaining the same speed, and the string tilts by an angle of Find the value of
The gravitational acceleration is
A rock tied to a string is moving at a constant speed of in a circle. If the rock's acceleration is what is the approximate radius of the circle it moves in?
