Galois drove 60.0 kilometers due west in 5.03 hours and then drove 43.0 kilometers dee north in 3.00 hours [a) How far did he travel? (b) What was his average speed? (e) When was his displacement? (d) What was his average velocity? 3. Find the total mass of two objects that weigh 314 newions and 271 newtons. 4. Find the density of a bos whose weight is 3893.40 newtons and whose volume is 4.60 cubic meters. Will it float in a liquid whose density is 90 kilograms per cubic meter? 5. The 250-newion force is a venical force, as shown. This system of forces is in equilibrium. Find the values of 7, and 72. SSON 6. The surface temperature on the moon has a range of -274-F to 403 kelvins. 212: 100" Bolling (a) Use the drawing on the right to help you convert-274"F to de- grees Celsius 180 100 [b) Convent 403 kelvins to degrees Celsius Freezing 7. An object moving in the positive . direction went from a velocity of 89 m/s to a velocity of 19 m/ in 7.0-seconds. When was the object's average acceleration? 8. A car traveling in a straight line goes 20 kilometers:in 13 minutes. What is its average speed In kilometers per hour? 9. A block is pulled to the right across a level surface at a constant velocity by a horizontal force of 48 newtons, as shown, The weight of the block is 91 newtons. What is the coefficient of kinetic friction between the block and the surface? 10. A block has a mass of 81.0 kilograms. The coefficient of static friction between the block and the level floor on which it rest is Q.621. A horizontal force of 398 newions is applied to the block to the right, as shown. Will the block move
