Answer:

Explanation:

ME=mvh

m=0.0780kg

v=4.84ms⁻¹

h=5.36m

ME=0.0780*4.84*5.36

ME=2.02joules

Answer:

5.01 J

Explanation:

ME = KE + PE

ME = ½ mv² + mgh

ME = ½ (0.0780 kg) (4.84 m/s)² + (0.0780 kg) (9.8 m/s²) (5.36 m)

ME = 5.01 J

The barometer of a mountain hiker reads 930 mbars at the beginning of a hiking trip and 780 mbars at the end. Neglecting the eff
lara31 [8.8K]
We could use the change of pressure to calculate for the height climbed by the mountain hiker. The change of pressure is given by

p = rho * g * h, where p is the change of pressure, rho is the air density, g is the acceleration due to gravity, and h is the height.

Using the conversion 1 mbar = 100 Pa,

(930 - 780)(100) = (1.20)(9.80)h
15000 = 1.20*9.80*h

h = 1.28 km
