Two projectiles are launched from a cliff of height H = 16m as shown in the diagram below. Projectile 1 is launched with velocity v1 = 12 m/s at an angle q1, where q1 = 35 degrees. Projectile 2 is launched with velocity v2 = 12 m/s at an angle q2, where q2 = 50 degrees. The next six questions pertain to this physical situation. 9) If the projectiles are lauched at the same time, which projectile lands first? Projectile 1 lands first. Projectile 2 lands first. The projectiles land at the same time. 10) What is the maximum height of projectile 2 above the ground?(not from the top of the cliff) y = 7.9 m y = 11.3 m y = 20.3 m y = 26.0 m y = 38.4 m 11) At the top of projectile 2's path, what is its speed? v = 0 m/s v = 5.6 m/s v = 7.7 m/s v = 9.8 m/s v = 12.0 m/s 12) How far from the cliff does projectile 2 land from the base of the cliff? x = 19.1 m x = 22.9 m x = 27.5 m x = 30.1 m x = 31.3 m 13) Right before projectile 2 hits the ground, what is its speed? v = 0 m/s v = 12.0 m/s v = 18.7 m/s v = 21.4 m/s v = 30.3 m/s 14) Which projectile lands farther away? Projectile 1 lands farther away. Projectile 2 lands farther away. The projectiles land at the same distance from the cliff. 15) A car's initial velocity is along the -x (negative x) direction. As it slows to a stop, its acceleration: is zero points in the +x direction points in the -x direction
