A 1.0 kg object is attached to a 0.50 m string. It is twirled in a horizontal circle above the ground at a speed of 5.0 m/s.
7nadin3 [17]

Given that,

Mass of the object, m = 1 kg

It moves in a circle of radius 0.5 m with a speed of 5 m/s

To find,

The direction of the acceleration.

Solution,

Whenever an object moves in a circular path, the only force that acts on its is centripetal force which is given by the formula as follows :

F=\dfrac{mv^2}{r}

The centripetal acceleration acts in the direction of force. It acts along the radius of the circular path. In this figure, the direction of the acceleration is shown at point d.

a stone falls from a ledge and takes 8 seconds to hit the ground the stone has an original velocity of 0m/s how tall is the ledg
gregori [183]
<span>Time until a stone hits the ground :t=8s. Initial velocity of the stone:vi=0m/s. We have to calculate the height of the ledge. Formula for this is: h=vi * t + g*t^2*2, where g=9.81 m/s^2. h=g*t^2/2. h=9.81 m/s^2*(8s)^2/2, h=9.81 m/s^2*64 s^2/2, h=9.81*32m, h=313.92 m. Answer: The ledge is 313.92 m tall. </span>
