Question

Someone please help me! And I will mark you as brainlist!!

1) A ball with a mass of 2.0 kg is thrown upward 1.2m calculate its gravitational potential energy into two significant figures. Gravity = 9.8 N/kg

• 2.4 J
• 1.4 J
• 120 J
• 24 J

2) Translation kinetic energy is defined as the energy of a system due to the motion of the system’s…

• center of mass
• axis of symmetry
• molecules
• rotational movement

PLEASE HELP!!

    Answer:

    1. G.P.E = 24 J

    2. center of mass

    Explanation:

    Given the following data;

    Mass = 2kg

    Height, h = 1.2m

    Acceleration due to gravity = 9.8 N/kg or m/s².

    To find the gravitational potential energy;

    Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.

    Mathematically, gravitational potential energy is given by the formula;

    G.P.E = mgh

    Where;

    • G.P.E represents potential energy measured in Joules.
    • m represents the mass of an object.
    • g represents acceleration due to gravity measured in meters per seconds square.
    • h represents the height measured in meters.

    Substituting into the formula, we have;

    G.P.E = 2*1.2*9.8

    G.P.E = 23.52 to 2 S.F = 24 Joules.

    Translation kinetic energy is defined as the energy of a system due to the motion of the system’s center of mass. The center of mass is typically where the mass of the object or particle is concentrated.
