Answer 2

Answer:

The force due to friction will be equal to 0.4N

Explanation:

• From the definition of force, we know

• F = ma

• We also know that, a = ( Vi-Vf)/t

• Putting the value in above equation, we get

• F = m*(Vi-Vf)/t)

• Putting the value

• F = 200*(30-10)/5

• F = 400gms-2

• We need to convert it to kg to make Neuton

• F = 0.4 kgms-2/0.4N
