friction between block and surface is 0.60‚ what was the speed of the bullet immediately before impact? 3. A ball bounces upward from the ground with a speed of 14 m/s and hits a wall with a speed of 12 m/s. How high above the ground does the ball hit the wall? Ignore air resistance. 4. A 200 g mass is attached to a spring of spring constant k. The spring is compressed 15 cm from its equilibrium value. When released the mass reaches a speed of 5 m/s. What is the spring constant (in N/m)? 5.

Introduction The UK government set up High Speed 2 (HS2) Ltd in January 2009 to consider the case for new high speed rail line between London and Scotland capable of carrying passenger trains at speeds up to 250 miles per hour. The broad plan for the network to Manchester and Leeds including the section between London and the West Midlands is roughly the shape of a letter Y. The “Service specification assumptions for the Y network” shows a total of 18 trains per hour (tph). The government and its
