Question

A man of mass of 50 kg jumps to a height of 1 m. His potential energy at the highest point is (g = 10 m/s2):

  1. 50 J

  2. 500 J

  3. 5 J
  4. 5000 J

hintHint:

Potential energy can be calculated mgh

The correct answer is:

500 J


    Given: 
    Mass of man (m) = 50kg
    Height (h) = 1m
    To find:
    Potential energy=?
    Solution:
    P E space equals space m g h space
P E space equals space 50 space cross times space 10 space cross times 1 space
P E space equals space 500 J
    Answer:
    Potential energy of the man is 500J

    What is the mass of a body whose weight is 49 newtons?

    The correct option is d)5 kg.
    The weight of the body = 49 N
    Weight of body = mass of body x gravity
    49= mass x 9.8
    mass = 49/9.8 = 5 Kg

    Two objects of different masses falling freely near the surface of the earth would:

    The correct option is a)Have same velocities at any instant.
    In free fall, velocity depends only on acceleration due to gravity. Acceleration due to gravity is independent of the mass of the object. Therefore, the gravitational pull of the moon applies the same acceleration to both objects. Therefore, it will always have the same velocity regardless of mass. The force depends on the mass, and since the bodies have different masses here, no two will experience the same force.

    Why does the earth not seem to move towards an apple falling towards it?

    The correct option is c)The acceleration gained by the earth is not sufficient for its motion to be apparent.
    Acceleration is inversely proportional to mass, so gravitational acceleration can be ignored.
    The apple falls to the earth, but the earth does not move towards the apple because acceleration is inversely proportional to mass. The Earth's mass is very large compared to the apple, so the acceleration towards the apple is negligible.
