Hey kids, sorry I didn't have internet access yesterday and I wasn't able to type up the problems.
3.30: An athlete executing a long jump leaves the ground at a 30degree angle and travels 7.90m. (a) What was the takeoff speed? (b) If this speed were increased by just 5.0 percent, how much longer would the jump be?
3.32 A hunter aims directly at a target (on the same level) 120 m away. (a) If the bullet leaves the gun at a speed of 250 m/s, by how much will it miss the target? (b) at what angle should the gun be aimed so the target will be hit?
3.34 A projectile is fired with an initial speed of 40.0 m/s. Plot (on graphing paper) its trajectory for initial projection angles of 15degrees, 30 degrees, 45 degrees, 60 degrees, 75 degrees and 90 degrees. Plot at least 10 points on each curve.
don't forget our "surprise" tomorrow on free body diagrams ;)

problem set 2
4.50. An athlete whose mass is 90.0 kg is performing weight-lifting exercises. Starting from the rest position, he lifts, with constant acceleration, a barbell that weighs 490 N. He lifts the barbell a distance of 0.60 m in 1.6 s.
a.) Draw a clearly labeled free-body diagram for the barbell and for the athlete.
b.) Use the diagrams in part (a) and Newton's laws to find the total force that his feet exert on the ground as he lifts the barbell.
4.52. A student tries to raise a chain consisting of three identical links. Each link has a mass of 300 g. The three-piece chain is connected to a string and then suspended vertically, with the student holding the upper end of the string and pulling upward. Because of the student's pull, an upward force of 12 N is applied to the chain by the string.
a.) Draw a free-body diagram for EACH of the links in the chain and also for the entire chain considered as a single body.
b.) Use the results of part (a) and Newton's laws to find (i) the acceleration of the chain; and (ii) the force exerted by the top link on the middle link.
LONG EXAM 1 IN PHYSICS 101
BRING THE FOLLOWING:
- BLUEBOOKS
- SCIENTIFIC CALCULATORS
REMINDERS:
-please review on circular motion and frictional forces
-solve problems also (this will help you)
