41. An arrow (m = 5.0 g) is red at a Styrofoam block (m = 150 g) sitting on the edge of a frictionless table. The tabletop is 1.1 m above ground. The arrow enters the block horizontally at V3] = 35 mils and passes through to the other side, exiting horizontally at v2.2 = 15 mats. (6 marks) a} Determine the speed of the Styrofoam after the arrow exits the block. (2 marks) in) Determine where the Styrofoam will land with respect to the arrow. Assume the arrow passed right through the centre of mass of the block, and both objects drop the same vertical distance to the ground. (4 marks) 42. Calculate the electric potential a distance 5.6 x 10" km from a point charge of 3.6 x 10\"1 C. [2 marks]
