A15 kg kangaroo jumps with an upward acceleration of 3 m/s2 by pushing hard off the ground.
a) draw a fbd for the kangaroo as it jumps. (which way must the net force point? )

How is acceleration calculated? a. initial velocity - final velocity / timeb. initial velocity + final velocity / timec. final velocity - initial velocity / timed. final velocity / timele select the best answer from the choices provided0oood00save and exitnextmark this and return

What was the first instrument to ever record an earthquake?

Panel bc in fig. p2.76 is semi-circular, with the 3 meter radius and horizontal straight edge through point b. compute (a) the hydrostatic force of the water on the panel, (b) its center of pressure, and (c) the moment of this force about point b. assume atmospheric pressure on the dry side of the panel
