A 9 kg 9 \text{ kg} body is projected horizontally at 12 m/s 12 \text{ m/s} from a height of 245 m. 245 \text{ m}. What is the magnitude of the body's vertical velocity when it strikes the ground?

The air resistance is negligible and the gravitational acceleration is g=10 m/s2. g = 10 \text{ m/s}^2.

A ball of mass 3 kg 3 \text{ kg} is projected from the ground with a velocity of 30 m/s 30 \text{ m/s} in a direction that makes a 30∘ 30 ^\circ angle with the horizon. How far does the ball fly horizontally?

Ignore any air resistance and assume that gravitational acceleration is g=10 m/s2. g = 10 \text{ m/s}^2.

A body of mass 2 kg 2 \text{ kg} is projected horizontally with a velocity of 3 m/s 3 \text{ m/s} from a height of 45 m. 45 \text{ m}. How far does the body fly horizontally?

Ignore any air resistance and assume that gravitational acceleration is g=10 m/s2. g = 10 \text{ m/s}^2.

A body of mass 6 kg 6 \text{ kg} is projected horizontally with a velocity of 12 m/s 12 \text{ m/s} from a height of 80 m. 80 \text{ m}. How long does it take for the body to touch the ground?

The air resistance is negligible and the gravitational acceleration is g=10 m/s2. g = 10 \text{ m/s}^2.
