Question

Net 15.04 4. An object of mass M = 12.0 kg is moving in the + x direction. As it passes the point x = 0, its speed is 5.00 m/s. The graph shows the net force, which points in the + x direction, that is acting on the object. Calculate: a) The net work done on the object as it moves from x=0 to X = 5.00 m b) The speed of the object as it passes the point x = 5,00 m. X (m) 3.00 The constant acceleration of the object as it moves from X=0 to x = 3.00 m. d) The velocity of the object as it passes the point x = 3.00 m. e) The time required for the object to move from x = 0 to x = 3.00 m. 1) The net impulse on the object as it moves from x = 0 to x 3.00 m. Net Force (N) 5.00
