Here's the question:

A 2.0 kg ball swings in a vertical circle on the end of an 80-cm-long string. The tension in the string is 20 N when its angle from the highest point on the circle is theta = 30 degrees.

(a) What is the ball's speed when theta equals 30 degrees? (in m/s)

(b) What is the magnitude of the ball's acceleration when theta equals 30 degrees? (in m/s^2)

  • velocity, acceleration, distance

    A ball is thrown vertically upward from the surface of the earth. Consider the following quantities: (1) the speed of the ball; (2) the velocity of the ball; (3) the acceleration of the ball.

  • Motion in two dimensions: Projectile motion.

    Here we can solve the motion separately in horizontal and vertical directions. When the ball falls the only force acting on it is its weight vertically down and due to that the acceleration is the acceleration due to gravity 9.8 m/s2.

  • Newton's Laws of Motion

    Prob. 10 : Action is the hitting force exerted by the bat on the ball. Its effect is to impart acceleration to the ball. Reaction is the equal and opposit force exerted by the ball on the bat as a result of which the bat tends to move backwards.
