4 A man is shot out of a cannon at a 40 o angle at 30.0 m/s. What is the man’s maximum altitude above the crowd?

Week 35 A man is shot out of a cannon at a 40 o angle at 30.0 m/s. How long is the man in the air?

Week 36 A man is shot out of a cannon at a 40 o angle at 30.0 m/s. How far away should we put the net to catch him?

Week 37 You’re a shot putter. You let go of the shot put 1.5m above the ground at a 42.5 o angle with an initial speed of 10 m/s. How far will the shot put go before hitting the ground?

Week 38 A bullet is shot horizontally from a rifle at 300 m/s and hits a tree 50 meters away. The person shooting is holding the gun 5 feet (1.5 meters) above the ground. How far from the ground is the bullet hole in the tree?

Week 39 A rocket drifts sideways in outer space from point “a” to point “b” as shown. Starting at position “b”, the rocket’s engine is turned on and produces a constant thrust at right angles to the line “ab”. The constant thrust is maintained until the rocket reaches point “c” in space. Which of the paths below best represents the path of the rocket between points “b” and “c”?

Week 310 QUIZ! Each group take a launcher and tape measure Choose an angle and set your launcher to that angle. If launcher has a piece of tape, v i = 6.7 m/s If no tape, v i = 6.3 m/s Calculate how far away you need to be to hit a target at the same height. Turn in calculations when done and help other groups. When all calculations are done, get ball, rod and safety glasses for launching.

Week 323 LAB 3 OBJECTIVES To develop a method for measuring forces reliably. To learn how to use a force probe to measure force. To explore how the motion of an object is related to the forces applied to it. To find a mathematical relationship between the force applied to an object and its acceleration.

Week 324 You’re pulling your kid sister in a wagon and she wants you to go faster. Graph the wagon’s position, velocity, acceleration and net force vs time as you make the wagon speed up.
