If a 50 kg student is standing on the edge of a cliff. Find the student’s gravitational potential energy if the cliff is 80 m hi
1 answer:
Answer:
Student’s(50 kg) gravitational potential energy if the cliff is 80 m high = 39.2 kJ
Explanation:
Potential energy is given by the expression, PE =mgh, m is the mass, g is the acceleration due to gravity value and h is the height.
Here mass of student, m = 50 kilogram
Height of cliff , h = 80 meter
Acceleration due to gravity =
Potential energy, PE = 50 * 9.8 * 80 = 39200 J
= 39.2 kJ
Student’s(50 kg) gravitational potential energy if the cliff is 80 m high = 39.2 kJ

The time the truck must apply the given force to increase its speed to given value is 5 s.
The given parameters;
- <em>applied force, F = 600 N</em>
- <em>mass of the truck, m = 1,500 kg</em>
- <em>speed of the truck, v = 2 m/s</em>
The force applied to the truck is determined by Newton's second law of motion; <em>which states that the force applied to an object is directly proportional to the product of mass and acceleration of the object.</em>
F = ma
Thus, the time the truck must apply the given force to increase its speed to given value is 5 s.

V
Remember that w=mg where w is weight in Newtons, m is mass in kilograms, and g is gravity in
m/s2
. For example, for Earth, 445 N = 45.4 × 9.8
m/s2
:Notice that the x-axis values will be gravity in
m/s2
, which is already given in the table, and the y-axis values will be the weight in Newtons. Remember to round your weights to a whole number, and to enter the points starting with the lowest gravity (moon, then Mars, then Venus, then Earth).
