Tarzan grabs a vine of length L=8.9 m and attempts to swing across the crocodile infested river. The vine breaks just as Tarzan is at lowest point of his swing, a horizontal distance D=60 m and H= 4.5 m above the riverbank. You barely mix it across, landing on the edge of the riverbank. The tension in the vine when it broke was a 1000 N. Find Tarzan's mass.
Maria sets up a simple track for her toy block (m 0.54 m Need Help? = (a) Neglecting friction, what is the speed of the block when it reaches the bottom of the curve (the beginning of the horizontal section of track)? 3.25 m/s 0.40 kg) as shown in the figure below. She holds the block at the top of the track, 0.54 m above the bottom, and releases it from rest. (b) If friction is present on the horizontal section of track and the block comes to a stop after traveling 0.82 m along the bottom, what is the magnitude of the friction force acting on the block? 2.11 X Your response differs from the correct answer by more than 10%.

A very light and flexible rope is 40 cm long and is at one end attached to the ceiling. When we hang a 100 gram weight on its other end, the rope is extended by 6.0 cm. The weight is then pulled vertically down so that the ropes length is 80 cm, and then we let go of it. How fast does the weight fly into the ceiling?
To form a pendulum, a 0.024 kg ball is attached to one end of a rod of length 0.70 m and negligible mass, and the other end of the rod is mounted on a pivot. The rod is rotated until it is straight up, and then it is released from rest so that it swings down around the pivot. When the ball reaches its lowest point, what are (a) its speed and (b) the tension in the rod? Next, the rod is rotated until it is horizontal, and then it is again released from rest. (c) At what angle from the vertical does the tension in the rod equal the weight of the ball? (d) If the mass of the ball is increased, does the answer to (c) increase, decrease, or remain the same? (a) Number i Units (b) Number i Units (c) Number i Units
A gymnast is swinging on a high bar. The distance between his waist and the bar is 1.28 m, as the drawing shows. At the top of the swing his speed is momentarily zero. Ignoring friction and treating the gymnast as if all of his mass is located at his waist, find his speed at the bottom of the swing.
An object is attached to a light string and is forced to move in uniform circular motion on a frictionless table. The radius of the circular path is 0.5m and the maximum amount of tension the rope can withstand without breaking is 16N. What is the maximum amount of kinetic energy this object can have?
Answer correctly the question: An m=3.84kg block situated on a rough incline is connected to a spring of negligible mass having a spring constant of k=100. N/m. The pulley is frictionless and massless. The block starts at rest at the position where the spring is unstretched. The block moves 15.1 cm down the incline before coming to rest. Take θ=38.8 as the angle. Calculate the coefficient of kinetic friction between block and incline. The answer is not 0.29

You are pushing your brother on a swing that has chains which are 3.5 m long. Treating the swing as a simple pendulum, how often should you push your brother so that he reaches the greatest height?
3. Imagine building a large pendulum by attaching one end of a 3.25-meter-long cable to the ceiling and the other end to a bowling ball that weighs 64.5 N. If you pull the ball to the side, it will swing back and forth in a circular arc. In one experiment you measure the speed of the swinging ball to be 4.25 m/s as it passes through its lowest point (when the cable is vertical). At that moment, find a. the magnitude and direction of the ball's acceleration b. the tension in the cable
An object with mass 0.60 kg is suspended from the ceiling at the end of a 2.0 m long string. When the mass is pulled to the side (at an unknown angle) and released, you measure the speed to be 4.0 m/s at the lowest point of its path. What maximum angle does the string make with the vertical as the object swings up? Note: air resistance can be ignored. Options 69 degrees 77 degrees 47 degrees 61 degrees 54 degrees 50 degrees
