2. Calculate the net work done for each situation. a) The net force on an object is 48 N, causing the object to move a distance of 32 m in a direction 30.0 away from the net force. 13] b) A 25.0 kg object which is moving with a speed of 24.0 m/s is acted on by a net force which results in the object to move with a speed of 40.0 m/s. /3] c) A 70.0 kg object moves upwards with an acceleration of 2.4 m/s', from a height of 20.0 m to a height of 80.0 m. /3]
