Amass m=8,5 kg ball is swinging in a vertical circle of radius r=23cm If the constant speed of the ball is v=5m/s Determine the tension in the string at the bottom of the circle in units of N(Newton). Take g=9.8m/s^2 and round off your result to 1 decimal place. Yanit: square

To determine the tension in the string at the bottom circle, we need to consider both the centripetal force and the gravitational force acting on the ball.At the bottom of the circle, the tension in the string is the sum of the centripetal force and the gravitational force.The centripetal force can be calculated using the formula: where is the mass of the ball, is the constant speed of the ball, and is the radius of the circle.The gravitational force can be calculated using the formula: where is the mass of the ball and is the acceleration due to gravity.The total tension in the string at the bottom of the circle is the sum of the centripetal force and the gravitational force: Substituting the given values: Rounding off to 1 decimal place, the tension in the string at the bottom of the circle is approximately 942.4 N.
