A = 3, B = 9, C = 18. A (1.25+A) kg bowling ball is hung on a (2.50+B) m long rope. It is then pulled back until the rope makes an angle of (12.0+C) degrees with the vertical and released. Find the speed of the ball is at the lowest point. Give your answer in m/s and with 3 significant figures.

Expert Solution

mass of the ball, m = (1.25 + A) Kg = (1.25 + 3) Kg = 4.25 Kg

length of the rope, L = (2.50 + B) m = (2.50 + 9) m = 11.5 m

angle made by the rope, θ = (12.0 + C) degrees = (12.0 + 18) degrees = 30.0 degrees

speed at the highest point is 0 m/s². So the kinetic energy at the highest point is, K.E._high = 0 Joule

Let the speed at the lowest point is u. So the kinetic energy at the lowest point is, K.E._low = ( m u² / 2 ) Joule

Please give a thumbs up if you are satisfied with the solution.

A 7.25-kg bowling ball moving at 8.5 m/s collides with a 0.825-kg bowling pin, which is scattered at an angle of θ = 24.5° from the initial direction of the bowling ball, with a speed of 11 m/s.Calculate the direction, in degrees, of the final velocity of the bowling ball. This angle should be measured in the same way that θ is. Calculate the magnitude of the final velocity, in meters per second, of the bowling ball.

Calculate the terminal velocity in free fall of a bowling ball (mass of 7.2 kg, diameter of 21.6 cm) and a basketball (mass of 0.51 kg, diameter of 23.85 cm). The bowling ball can be considered a smooth sphere (Cd = 0.1), while the basketball can be considered a rough sphere (Cd = 0.4). What would be the terminal velocity of the basketball if we considered it a smooth sphere?
