A body of mass m experiences an initial acceleration a when a certain net force acts on it.
(a) Predict the new acceleration if the net force alone is doubled, keeping the mass unchanged.
(b) Predict the new acceleration if the mass alone is halved, keeping the net force unchanged.
(c) Predict the new acceleration if the net force is halved and the mass is doubled simultaneously.
Express each answer as a simple multiple or fraction of a.
a. Predict the new acceleration if the net force alone is doubled, keeping the mass unchanged.
b. Predict the new acceleration if the mass alone is halved, keeping the net force unchanged.
c. Predict the new acceleration if the net force is halved and the mass is doubled simultaneously.
