Question

PHY 2053 Test #1 2019-01-30 2. A projectile is launched from the top of a building an angle 0 at an initial velocity o 16.25 s at 0,510.850 above the horizontal direction. The projectile strikes the level ground orizontal distance of R- 222 m from where it launched. Ignoring air frictio (a) Cal (b) Calculate the time of flight of the projectile in the air (c) How high is the building above the ground? (d) What are the horizontal and vertical components of the projectile's velocity u as it culate the horizontal and vertical components of the projectile's initial velocity to strikes the ground? e) What is the magnitude of the projectile's velocity as it strikes the ground? (T) What is the angle between the projectile's velocity i and the positive x-direction at the instant it strikes the ground? (g) Find the magnitude and direction of the projectile's acceleration at the instant imme- diately before it strikes the ground
