Explanation:

  • Case 1

Force = Mass × Acceleration

f \:  =  \: m \: a

f \:  = 5 \times 10

f \:  = 50  \: \: newton

  • Case 2

f \:  = m \: a

a \:  =  \frac{f}{m}

a \:  =  \frac{50}{8}

a \:  = 6.25 \: m \:  {s}^{ - 2}

Answer:

  • For a body moving with uniform retardation.  Force acting on a body of mass 5kg produces acceleration 10\ m/s^{2} will be 50\ N
  • For the mass of 8 kg, the same force will produce an acceleration of 6.25\ m/s^{2}

Explanation:

Newton's second law of motion states that,

Force applied (F) will be the product of mass and acceleration.

If 'm' is the mass of the object and 'v' is the velocity, then it can be expressed as,

F = ma   ...(1)

By rearranging the above equation,

a = \frac{F}{m} ...(2)

Negative acceleration is called retardation.

In the question, it is given that,

m = 5\ kg

a =  10\ m/s^{2}

Substitute these values into equation(1),

F = 10\times 5 = 50 N

If the same force acts on another body,

m = 8\ kg    F = 50N

Using equation (2),

a = \frac{50}{8}  = 6.25\ m/s^{2}
