What are the givens and the unknowns for the situation below? jose wandered a total of 13 kilometers starting at 2 kilometers per hour, but at a velocity of 5 km/hr at the end. how long did jose wander?
a. given: initial velocity, time, final velocity. need: acceleration
b. given: initial velocity, final velocity, acceleration. need: displacement
c. given: displacement, initial velocity, final velocity. need: time
d. given: displacement, time, initial velocity. need: final velocity

When seismic waves hit a fault, the waves are reflected off the fault. seismograph can detect these reflected seismic waves. geologists then use these data to map the fault's length and depth

Iwould think it is temperature, silica, oxides (gases)

Distance covered, s = 8ft - 4ft = 4 ftinitial velocity, u = 34 ft/sthe acrobat is moving upwards and therefore, a = -g = -9.81 m/s^2 = 32.19 ft/s^2applying equation of motion; s = ut -1/2gt^2then,4 = 34t -1/2*32.19t^24 = 34t - 16.095t^2rearranging; -16.095t^2 + 34t - 4 = 0solving the quadratic equation; t = {-34 +/- sqrt [34^2 - 4(-16.)]}/2(-16.095) = 1.06 +/- 0.93 = 0.13 or 1.99the acrobat will take 0.13 seconds to be at 8 ft above the ground. additionally, once at the maximum height, the acrobat will move down and be at the same spot (that is height) after 1.99 seconds moving down.
