Q1. A 13g bullet travelling 233 m/s penetrates the 2.0kg block of wood and emerges going 175 m/s. If the block is stationary on the frictionless surface when hit, how fast does it move after the bullet emerges?

Q2. Therefore of his observations, Ole Roemer concluded that eclipses of Io by Jupiter were delayed by 22 min throughout a six-month period as the Earth moved from the point in its orbit where it is closest to Jupiter to the diametrically opposite point where it is farthest from Jupiter. Using the value 1.50 x 10^8 km as the average radius of the Earth's orbit around Sun, calculate the speed of light from these data.
