<span>We can use a simple equation to calculate the increase in gravitational potential energy.
PE = mgh
m is the mass of the object
g is the acceleration due to gravity
h is the change in height
PE = mgh
PE = (3.75 kg) (9.80 m/s^2) (1.5 m)
PE = 55.1 Joules
The increase in gravitational potential energy is 55.1 Joules.</span>
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
Answer:
Explanation:
Given that,
Force force acting on the Skater's rocket is 220 N
Resistive force acting on it, F' = 30 N
Mass of Shelby, m = 60 kg
We need to find the acceleration of Shelby. Net force acting on Shelby is given by :
Net force = 220-30
= 190 N
The formula of net force is :
F = ma
a is acceleration of Shelby
So, the acceleration of Shelby is
