What is the student’s maximum speed ? A 80kg student bungee jumps off a bridge as shown using an ideal bungee cordwith a spring constant of 17N/m. The natural length of the bungee cord is shown.Neglect energy gained from the jump and neglect loss until the student rebounds.How long is the cord when she reaches maximum speed?89.142mWhat is the student's maximum speed?m/sHint: The student stops gaining speed when the spring force is equal to her weight. Find this location, thenapply conservation of energy with the reference level at this height.What is the length of the cord when the student reaches her lowest point?mHint: Set up an equation for conservation of energy in terms of the stretch length (x) and givens only. Thensolve the quadratic.

The maximum ('terminal') velocity, vt, that a falling object achieves depends on its mass m, the acceleration g due to gravity, the density p of the air, the object's frontal area A, and the object's drag coefficient C, which is a dimensionless quantity. The equation for the terminal velocity is: 2mg V = pCA Part (a): A skydiver jumps out of an airplane (regrettably) without his parachute. To slow his descent, he orients himself in a 'spread eagle' position, thereby increasing his area A to 0.70 m?. His drag coefficient Cis 1.0, which is a unitless quantity. Calculate his terminal velocity in m/s if his mass is 85 kg, the air density p is 1.21 kg/m3, and the constant g is 9.80 m/s?. Show your work, and ensure that each numeric value has the appropriate units. Your answer should be rounded to the appropriate number of significant digits. Part (b): Convert the answer from part (a) to miles per hour using the dimensional analysis method we reviewed in class. Show your work, and ensure…

At the base of a hill, a 90 kg cart drives at 13 m/s toward it then lifts off the accelerator pedal). If the cart just barely makes it to the top of this hill and stops, how high must the hill be?
a bobsled is moving with a velocity of 24.5m/s. the brakes are then applied and the sled begins to slow with acceleration of 3.7m/s2 . assume that the braking area has a length of 85m, will the sled be able to stop before it runs out of room? if not, how much space is remaining?
