# Projectile motion - beginners

A $$9 \text{ kg}$$ body is projected horizontally at $$12 \text{ m/s}$$ from a height of $$245 \text{ m}.$$ 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 $$g = 10 \text{ m/s}^2.$$

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

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

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

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

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

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

A body of mass $$6 \text{ kg}$$ is projected horizontally with a velocity of $$45 \text{ m/s}$$ from a height of $$180 \text{ m}.$$ Find the magnitude of its velocity at the moment it touches the ground.

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