2. A block is moving horizontally at a constant velocity of 5m/s. A 25N force is applied to the block for 2 seconds as shown. Due to this, the block's velocity increased with an acceleration of 0.5m/s². The coefficient of friction between the floor and the block is 0.3. Determine the following: a. Velocity of the block right before the 25N force is removed. (m/s) b. Mass of the block. (kg) c. Friction force. (N) 25N m H = 0.3
