Practice Questions

Question 1

A projectile is launched with an initial velocity of $u$ at an angle of $\theta$ above the horizontal. What is the expression for the maximum height ($H$) reached by the projectile?

Question 2

A projectile is launched from the ground with an initial velocity of $40 \text{ m/s}$ at an angle of $30^\circ$ above the horizontal. What is the horizontal range of the projectile? (Assume $g = 10 \text{ m/s}^2$)

Question 3

A ball is thrown horizontally from a height of $20 \text{ m}$ with an initial velocity of $15 \text{ m/s}$. How long does it take for the ball to hit the ground? (Assume $g = 10 \text{ m/s}^2$ and no air resistance)

Question 4

A projectile is launched at an angle $\theta$ above the horizontal. If the initial speed is $u$, what is the magnitude of the velocity of the projectile just before it hits the ground, assuming it lands at the same height from which it was launched and ignoring air resistance?

Question 5

A projectile is launched from the ground with an initial velocity of $20 \text{ m/s}$ at an angle of $60^\circ$ above the horizontal. What is the time it takes to reach its maximum height? (Assume $g = 10 \text{ m/s}^2$)
