Number 3 show all work 1) A 1.50-kg block is moved at constant speed in a vertical plane from position 1 to position 3 via severalroutes shown in the figure. Compute the work done by gravity on the block for each segment indicated,where Wab means work done from a to b. (a) W13, (b) W, 2 + W23 (c) W14 + W43, (d) W,4 + W45 + Wg3 m3 m2 m122) What is the work needed to lift 14.7 kg of water from a well 11.0 m deep. Assume the water has a constantupward acceleration of 0.700 m/s?.3) The variation of a force with position is shown in the figure below. Find the work from (a) x = 0 to x =-A (b) x = +A to x = 0F.FoF4) Whe wo 85-kg persons sit in a 1000-kg car, it is lowered by 2 cm. Estimate the spring constant of thesuspen. n. What simplifying assumptions do you need to make?5) A spring gun with k= 90.0 N/m is compressed by 5 cm. What is the exit speed of a 2.10-g projectile?6) (a) The United States, with a population of 2.2×10 people, consumes 5×10 1ºJ per year. What is the percapita consumption in watts? (b) The sun's radiation provides the earth with 1000 W/m². Assuming solarenergy can be converted to electrical energy with a 20% efficiency, how much area is needed to serve theenergy needs of each U.S. citizen?7) A 0.595-kg object is released from a height of 3.60 m and lands on the ground. Find: (a) the work done bygravity; (b) the change in kinetic energy of the ball; (c) the speed just before it lands using energy methods.Ignore air resistance.
