Question

2. A projectile is thrown from the top of a building with an initial velocity of 30 m/s in the horizontal direction. If the top of the building is 30 m above the ground, a) how long is the projectile in the air? b) With what speed and angle will the projectile be moving just before it strikes the ground? (Hint: final speed = 38.6 m/s)

Step 1

Given: Initial vertical velocity (Viy) = 0 m/s, acceleration due to gravity (ay) = 9.8 m/s^2 Using the formula: Vf = Vi + at 0 = 30 + (-9.8)t -30 = -9.8t t = 3.06 seconds Show more…
