A 4.0 kg projectile is launched into the air with an initial velocity of 15 m/s at an angle of 30° above the horizontal. When the projectile reaches its maximum height it explodes, splitting in two parts, one of mass 3.0 kg and one of mass 1.0 kg. Assume the explosion was essentially instantaneous.

  1. Determine the maximum height of the projectile using energy.

  2. After the explosion, if the 1.0 kg mass is moving at 1/2 the speed it was right

    before the explosion. Find the velocity of the 3.0 kg mass right after the explosion.

  3. How far from the launch site will the 3.0 kg mass land?

A streamlined and compact projectile is launched from flat ground on a valley toward a distant hillside at an Army testing ground in Nevada. The projectile’s initial speed is vi = 150. m/s as it leaves the cannon. The initial angle of launch θi of the projectile is unknown. The projectile makes impact high on the distant hill a time t = 3.00 s after its departure. From GPS sensors we know that the site of impact is a straight-line...

A 4-kg projectile travels with a horizontal velocity of 600 m/s before it explodes and breaks into two fragments A and B of mass 1.5 kg and 2.5 kg, respectively. If the fragments travel along the parabolic trajectories shown, determine the magnitude of velocity of each fragment just after the explosion and the horizontal distance where segment B strikes the ground at D.
