When the grasshoppers vertical velocity is exactly zero.
v = -g•t + v0.
v: vertical part of velocity. Is zero at maximum height.
g: 9.81
t: time you are looking for
v0: initial vertical velocity
Find the vertical part of the initial velocity, by using the angle at which the grasshopper jumps.
Answer:2738.477 kJ
Explanation:
Given
Lowest Point of death valley is 75.5 m below sea level
Height of Mt. Whitney is 4360 m
mass of hiker =63 kg
Change in potential energy
Considering sea level a datum
The answer is 34.775j because w=Fd (53.5N)(0.65m)=34.775j
answer:
liquids have he ability to change shape
liquids flow even with some resistance
liquids have a definite volume
liquids have molecules that slip past each other
Kinetic energy=0.5*mass*(velocity²)=0.5*70*5*5=875 J
