Question: QUESTION 6 A Projectile Is Launched From One Level And Lands At A Lower Level Such That Yo = H And Yf = 0 M. If The Projectile

QUESTION 6 A projectile is launched from one level and lands at a lower level such that Yo Hand YF Dm. If the projectie is launched at an angle of degrees and with an initial "muzzle velocity" of Vo mis, the horizontal velocity Vex is: A remaining constant at an initial value equal to Vo B. increasing from an initial value equal to Vo Cremaining constant at an initial value equal to Vo cos(8) Dremaining constant at an initial value equal to Vo sin() QUESTION 7 A projectile is launched from one level and lands at a lower level such that Yo Hand Y=0m. If the projectile is launched at an angle of degrees and with an initial "muzzle velocity of Vomis, the total time-of-flight is equal to A the larger of the two roots of the quadratic equation 0HVocos-1/2 g 1 Bson2 Vo sin C. D. the larger of the two roots of the quadratic equation OH Vo sin-1 sin1-1202 the larger of the two roots of the quadratic equation H+ Vosin(-1/2 QUESTION 8 A projectile is launched from one level and lands at a lower level such that Yo1.00 m and YF 0.00. If the projectile is launched at an angle of 65.0 degrees and with an initial "muzzle velocity of 5.50 m/s, the total time-of-flight is equal to 1.01 B.0.000 C 1.10 0.172 QUESTION 9 A projectile is launched from one level and lands at a lower level such that Yo 1.00 m and YF 0.00. If the projectile is launched at an angle of 65.05 os and with an initial "muzzle velocity" of 5.50 m/s, the horizontal displacement is equal to: A 3.88 m 8.5.40m C-3.04m 2.76 m QUESTION 10 To help minimize bodily harm to persons in the room during the projectile experiment A All of the answers are comect B. all persons present should be wearing their safety glasses the plastic "plunger should be used to load the ball properly into the projectile firing device D-care should be taken not to look directly into the projectile firing device, especially if loaded the plastic "plunger should be used to load the ball properly into the projectile fring device
