A moving body of mass 25.0kg undergoes a uniform retardation of 20.0ms-2. Calculate the magnitude of the retardating force

Answer Details

The force acting on an object is given by the formula F = ma, where F is the force, m is the mass and a is the acceleration. However, in this case, the object is undergoing retardation, which means its acceleration is negative. Therefore, we have a = -20.0ms^-2. The mass of the object is given as 25.0kg. Using the formula F = ma, we can calculate the magnitude of the force as follows: F = m x a = 25.0kg x (-20.0ms^-2) = -500N The negative sign indicates that the force is acting in the opposite direction to the motion of the object. However, since the question asks for the magnitude of the force, we take the absolute value, which is 500N. Therefore, the magnitude of the retardating force acting on the object is 500.00N. So, the answer is 500.00N.
