A small mass of 5g is attached to one end of a light inextensible string of length 20 cm and the other end of the string is fixed. The string is held taut and horizontal and the mass is released. When the string reaches the vertical position, what are the magnitudes of: (a) the kinetic energy of the mass, (b) the velocity of the mass, (c) the acceleration of the mass, (d) the tension in the string? (Neglect air friction.)

Assume that the force of a bow on an arrow behaves like the spring force. In aiming the arrow, an archer pulls the bow back 50 cm and holds it in position with a force of 150 N. If the mass of the arrow is 50 g and the “spring” is massless, what is the speed of the arrow immediately after it leaves the bow?
A mysterious force acts on all particles along a particular line and always points towards a particular point P on the line. The magnitude of the force on a particle increases as the cube of the distance from that point; that is Fr3 , if the distance from P to the position of the particle is r. Let b be the proportionality constant, and write the magnitude of the force as F=br3. Find the potential energy of a particle subjected to this force when the particle is at a distance D from P, assuming the potential energy to be zero when the particle is at P.
Jane, whose mass is 50.0 kg, needs to swing across a river (having width D) filled with person-eating crocodiles to save Tarzan from danger. She must swing into a wind exerting constant horizontal force F, on a vine having length L and initially making an angle with the vertical (Fig. P7.81). Take D = 50.0 m, F = 110 N, L = 40.0 m, and = 50.0. (a) With what minimum speed must Jane begin her swing to just make it to the other side? (b) Once the rescue is complete, Tarzan and Jane must swing back across the river. With what minimum speed must they begin their swing? Assume Tarzan has a mass of 80.0 kg.
1.0 kg Oo 2.0 kg 31° 9. At t = 1.0 s, a 0.55-kg object is falling with a speed of 6.5 m/s. At t = 2.0 s, it has a kinetic energy of 38 J. (a) What is the kinetic energy of the object at t = 1.0 s? (b) What is the speed of the object at t = 2.0 s? (c) How much work was done on the object between t = 1.0 s and t = 2.0s?
An object of mass 6.5 kg is released at point A, at a height of 2.0 m above the ground. It slides to the bottom of the 30°incline and eventually collides with a horizontal massless spring with the spring constant 720 N/m. If the horizontal surface and the incline is frictionless, then (a) What is the speed of the object at the bottom of the incline? (b) What is the maximum distance the block compresses the spring, before coming to rest? (c) How muck distance would the spring be compressed if %50 energy is lost to friction.

The resilin in the body of a flea has a forceconstant of about 24 N>m, and when the flea cocks its jumpinglegs, the resilin associated with each leg is compressed by approximately 0.12 mm. Given that the flea has a mass of 0.56 mg, andthat two legs are used in a jump, estimate the maximum height aflea can attain by using the energy stored in the resilin. (Assumethe resilin to be an ideal spring.)
