11) A model drag car is being accelerated along its track from rest by a motor with a force of 75 N, but there is a drag force of 30 N due to the track. What is the kinetic energy after 2 m of travel?

    The kinetic energy after 2 m is:

    90 J

    Explanation:

    Given that:

    Truck is accelerated from rest with force = F₁ = 75 N

    Drag force = F₂ = 30 N

    Distance = D = 2 m

    Sol:

    Kinetic energy is defined as the work done required to move a body from rest position to a specific velocity.

    We know that work done is equal to the force multiplied by the distance:

    Work done = Force x Distance

    W = F x D

    According to given situation, the above equation becomes:

    W = (F₁ - F₂) x D

    W = (75 - 30) x 2

    W = 90 J

    So, the kinetic energy is 90 J.
