A 30 kg projectile is launched from the ground at an initial velocity of 300 m/s at an angle of 45 degrees above the horizontal. If air resistance is ignored, determine the following:

a. The projectile's speed at 2000 meters above the ground.

b. The total amount of energy the object has at 3000 m.

c. The maximum height of the projectile.

d. The maximum distance the projectile travels horizontally.

Solutions

Expert Solution

Here we apply concept of kinematics and parabolic motion. We apply equation of motion for constant acceleration along horizontal and vertical directions separately.
