When a 2 kg ball is thrown with an acceleration of 40 m/s². The
force exerted on the ball is 80 N.
According to Newton's second law of motion
F = ma
where, F = force exerted on the object, m = mass of an object and a = acceleration of the object.
Here, m = 2 kg, a = 40 m/s². so, F = ?
Therefore, force (F) exerted on the ball = 40x2 = 80 N
