Answer:
v = 36.05 m/s
Explanation:
It is given that,
Initial speed of the parachutist, u = 14.8 m/s
Altitude, h = 55.1 m
The acceleration due to gravity,
Let v is the speed of the shoe just before it hits the ground. The third equation of motion is given by :
v = 36.05 m/s
So, the speed of the show just before it hits the ground is 36.05 m/s. Hence, this is the required solution.
It becomes faster because there is less weight being pulled
The sun crosses the plane of Earth's equator when the center of
the sun coincides with either of the two points on the map of the
sky labeled "equinox".
One of the following two phenomena occurs at that time, depending
on the direction in which the sun crosses the plane.
1). People all over the northern hemisphere shout and exclaim "It's Spring!",
whereas those in the southern hemisphere yell "It's autumn now.".
2). People all over the northern hemisphere yell "It's Autumn now.", whereas
those in the southern hemisphere shout and exclaim "It's Spring !".
Answer:
Thermal/Heat energy, kinetic energy, light energy, & Electromagnetic energy
Answer:
Potential energy is
Explanation:
The potential energy depends on the mass, the acceleration of gravity g and the height at which the object or person is.
Potential energy
In this case we would need to know the exact mass of the hiker in order to calculate the potential energy.
But we know the values of g and h
So, the potential energy
m is the mass of the hiker, wich is not in the description of the problem.
