Doc Al said:Use the kinematics of projectile motion to find the initial speed of the stone. Then use that speed to calculate the centripetal acceleration.
Speed is the measure of how fast an object is moving, while velocity is the measure of how fast an object is moving in a specific direction.
Mass is the measure of the amount of matter in an object, while weight is the measure of the force of gravity acting on an object.
Acceleration can be calculated by dividing the change in velocity by the change in time. The formula for acceleration is a = (vf - vi) / t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time.
Newton's First Law of Motion, also known as the law of inertia, states that an object at rest will remain at rest and an object in motion will remain in motion at a constant velocity unless acted upon by an external force.
Work can be calculated by multiplying the force applied to an object by the distance the object moves in the direction of the force. The formula for work is W = F * d, where W is work, F is force, and d is distance.
