Practice with Problems at Angles

Do Now : 

Do Now You throw an object at 20 m/s at 45 degrees above the horizontal. Find the x and y components of the object’s initial velocity? What will the object’s overall velocity be at the peak of its motion? What will the object’s overall speed be at the end of its motion? velocity?

Objective and Announcements : 

Objective and Announcements SWBAT… Solve complicated projectile motion problems Be ready for our outdoor adventure! Announcements We are going outside on Monday, bring good clothes for that.

Slide 6: 

You throw an object at 20 m/s at 45 degrees above the horizontal. Find the x and y components of the object’s initial velocity? What will the object’s overall velocity be at the peak of its motion? What will the object’s overall speed be at the end of its motion? velocity?

Slide 7: 

You throw an object at 20 m/s at 45 degrees above the horizontal. Find the x and y components of the object’s initial velocity? What will the object’s overall velocity be at the peak of its motion? What will the object’s overall speed be at the end of its motion? velocity?

Slide 8: 

You throw an object at 20 m/s at 45 degrees above the horizontal. Find the x and y components of the object’s initial velocity? What will the object’s overall velocity be at the peak of its motion? What will the object’s overall speed be at the end of its motion? X-velocity? 14.1m/s, horizontal velocity doesn’t change! Y-velocity? 0m/s! At the peak, the object comes to an instantaneous stop Total Velocity? 14.1m/s

Slide 9: 

You throw an object at 20 m/s at 45 degrees above the horizontal. Find the x and y components of the object’s initial velocity? What will the object’s overall velocity be at the peak of its motion? What will the object’s overall speed be at the end of its motion? What comes up must come down! What comes up must come down! 20 m/s 20 m/s

Slide 11: 

A bow and arrow must be pointed at 10 degrees above the horizontal to hit a target that is downrange on flat ground. If the arrow leaves the bow at 7 m/s, how far away is the target? Picture X Problem Y Problem Trig

Slide 12: 

A person jumps at 13 m/s at 50 degrees above the horizontal across a puddle. What is the widest puddle that the person could make it across? Picture X Problem Y Problem Trig

Slide 13: 

A ball is tossed off of a cliff 15 meter cliff at an unknown velocity and angle. A man with a velocity gun at the bottom of the cliff detects that the ball was moving vertically at 25 m/s down at the moment that it hit the ground 20 meters away from the cliff, what was the velocity and angle at which the bal was tossed? Picture X Problem Y Problem Trig
