Name: Date: Per: Physics Ch3: Projectile Motion, Wks 3.2 1. A drone is moving 8 m/s at a 30-degree angle in a 2 m/s west wind (i.e. wind moving from west to east). What is its velocity with respect to the ground? 2. An airplane is flying 100 mph at 45-degrees in a south wind (i.e. wind moving from south to north). What is its velocity w.r.t. the ground? 3. A boat is going 20 km/h at 50-degrees in a 10 km/h current at 35-degrees. What is the boat's velocity w.r.t. the Earth? 4 An airplane is going 500 mph northwest in a 100 mph wind at 30-degrees. What is the plane's velocity w.r.t. the Earth? 5. A marble rolls of a table at 1.5 m/s. If the table is 1.0 m high, how far from the base of the table will the marble land? 6. A bird flying at 12 m/s at a height of 20 m drops a "present" right over an "x." How far horizontally will the present land from the x? 7. A cannon fires a cannonball at 120 m/s at an angle of 60-degrees. a. How long will the cannonball be in the air? b. How far (horizontally) will the cannonball go? 8. An archer shoots an arrow at 55-degrees. If the arrow travels 50 m, total time is 4s a. How long will the arrow be in the air? b. How fast did the archer shoot the arrow? 9. *On a 105 m cliff, you throw a rock at 25 m/s an angle of 53-degrees. a. How high will the rock go? b. How long will the rock be in the air? c. How far from the base of the cliff will the rock land? 10. *You kick a football at 50-degrees & 50 m/s. If it lands on a platform 20 m high, a. How long will it be in the air? b. How high will it go? c. How far horizontally will it have travelled
