A projectile is launched at an angle of 20* above the horizontal with a launch velocity of 25 m/s. a.) What is the maximum height reached by the object? " b.) What is the total flight time (between launch and touching the ground) of the object? (3 c.) What is the horizontal range (maximum x above ground) of the object?

Two spheres A and  B (of mass m each) were fired vertically from the ground with different initial velocities at different times. When sphere A reached its summit, sphere B, with an upward velocity of 10.76 m/s, created a head-on collision with A. The impact caused sphere A to break into two pieces, each of mass m/2. Knowing one-piece reached Point  C and the other piece reached point  D after the collision, determine: (a) the velocity of sphere B after the collision; (b) the angle θ and the speeds of the two pieces after the collision; and (c) the force exerted by sphere A on B if the collision occurred in 0.001s.
