5g is moving horizontally with speed v o. Question 1: A bullet of mass m= hits a block of mass 100m that is at rest on a horizontál frictionless table, as shown in fig. 1. The surface of the table is a height h = 10m above the floor. After the impact, the bullet and the block slide off the table and hit the floor a distance x from the edge of the table. 600 m/s when it || (a) (3 marks) Find the speed of the block as it leaves the table. (b) (3 marks) Calculate the change in kinetic energy of the bullet-block system during impact. (c) (3 marks) Find the distance x. 100m Fig. 1

A trough is 5 meters long and 1 meter high. The vertical cross-section of the trough parallel to an end is shaped like the graph of y = x from x = -1 to x = 1. The trough is full of water. Find the amount of work (in joules) required to empty the trough by pumping the water over the top. (The acceleration due to gravity is 9.8 and the density of water is 1000 kg m³ m s²

You throw a ball of mass 1 kilogram upward from a height of 0 meters with a velocity of a = 23 m/s on Mars, where the acceleration due to gravity is g = 3.711 m/s. (a) Use your calculator to approximate how much longer (in seconds) the ball is in the air on Mars compared to on Earth where g = 9.80 m/s-. (Round your answer to three decimal places.) X S (b) Use your calculator to approximate how much higher (in meters) the ball went on Mars compared to on Earth. (Round your answer to one decimal place.) X m
