The maximum velocity she can reach when she skis to the bottom of the slope is
meters/second.
use pe = m × g × h, g = 9.8 m/s2, and . ignore air resistance and friction.

The height of the second hill is about 41.9 meters.

Explanation:

The car has 349,300 joules of energy at the top of the second hill. The mass of the car is 850 kilograms.

Plug the values for PE, m, and g into the formula, and solve for h:

349,300 = 850 × 9.8 × h

so h=349,300/850*9.8

h=41.9

because it is and it's just life man

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .
