PhysicsQ&A LibraryA ball with mass 0.18 kg is thrown upward with initial velocity 30 m/s from the roof of a building 40 m high. Neglect air resistance. (A computer algebra system is recommended. Use g = 9.8 m/s² for the acceleration due to gravity. Round your answers to one decimal place.) (a) Find the maximum height above the ground that the ball reaches. (b) Assuming that the ball misses the building on the way down, find the time that it hits the ground.Start your trial now! First week only $4.99!*arrow_forward*
