A bowling ball weighing 71.2 N is swinging like a pendulum at the end of a 3.8 m rope. As the ball swings through its lowest point, its speed is measured at 4.2 m/s. What is the magnitude and direction of the acceleration of the ball at this point?
Homework Answers
Here,
at the lowest point
there will be no tangential acceleration
the only acceleration is centripetal
hence , for the total acceleration
total acceleration = v^2/L
total acceleration = 4.2^2/3.8
total acceleration = 4.64 m/s^2
the acceleration is towards the center of circle
the magnitude of acceleration is 4.64 m/s^2 in upwards direction

A bowling ball weighing 71.2 NN is attached to the ceiling by a
3.50 mm rope. The ball is pulled to one side and released; it then
swings back and forth like a pendulum. As the rope swings through
its lowest point, the speed of the bowling ball is measured at 4.40
m/s.
Part A
At that instant, find the magnitude of the acceleration of the
bowling ball.
Part B At that instant, find the direction of the acceleration of...

A bowling ball weighing 71.2 N (=mg) is attached to the ceiling by a 3.40 m rope. The ball is pulled to one side and released; it then swings back and forth as a pendulum. The ball is initially pulled back so it is a vertical height of 2.2 m above the lowest point of the ball's swing. 1. When the ball is at its lowest point in its swing, what is the acceleration of the bowling ball, in magnitude...

A ball swings in a vertical circle at the end of a rope 1.50 m long. When the ball is 36.9° past the lowest point on its way up, its total acceleration is (-22.5120.2j) m/s2 For that instant, do the following. (a) Sketch a vector diagram showing the components of its acceleration. (Do this on paper. Your instructor may ask you to turn in the sketch.) (b) Determine the magnitude of its radial acceleration m/s2 (c) Determine the speed of...

A steel ball is tied to a long piece of string and the other end of the string is tied to a vertical support forming a pendulum. If the ball (called the pendulum's "bob") is pulled to the side and released, then the ball swings back and forth. What is the direction of the ball's acceleration when it is at the lowest point in its swing? As usual, we ignore the effect of air resistance. in the direction of the...

A 5.5-kg bowling ball is attached to the end of a nylon (Young's modulus 3.7 times 10^9 N/m^2) cord with a cross-sectional area of 3.3 times 10^-5 m^2. The other end of the cord is fixed to the ceiling. When the bowling ball is pulled to one side and released from rest, it swings downward in a circular arc. At the instant it reaches its lowest point, the bowling ball is 1.2 m lower than the point it was released...

An athlete swings a 3.70 kg ball horizontally on the end of a rope. The ball moves in a circle of radius 0.970 m at an angular speed of 0.740 rev/s. (a) What is the tangential speed of the ball? m/s (b) What is its centripetal acceleration? m/s2 (c) If the maximum tension the rope can withstand before breaking is 115 N, what is the maximum tangential speed the ball can have? m/s

A spherical bowling ball with mass m = 3.8 kg and radius R = 0.106 m is thrown down the lane with an initial speed of v = 8 m/s. The coefficient of kinetic friction between the sliding ball and the ground is p = 0.33. Once the ball begins to roll without slipping it moves with a constant velocity down the lane. 1) What is the magnitude of the angular acceleration of the bowling ball as it slides down...

A 5.75-kg bowling ball moving at 9.25 m/s collides with a 0.925-kg bowling pin, which is scattered at an angle of θ = 23° from the initial direction of the bowling ball, with a speed of 11.1 m/s. (a) 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. (b) Calculate the magnitude of the final velocity, in meters per second, of the bowling ball.
