A projectile is launched from the ground as shown in the figure below with an initial speed of vo = 45 m/s with θ = 62∘ and lands on the landing point shown. If X = 32 m, determine the height of the landing point. Take g = 9.81 m/s2 and express our answer in units of meters using one decimal place.

A projectile is launched from the ground with velocity |v→| = 5 m/s, at an angle θ = 63∘ from the horizontal direction. The projectile would have landed on the ground at the horizontal distance d1 away from the launch point, but instead it hit the top of a platform of height h in the way. The platform was hit at a horizontal distance d2 away from the launch point. If the projectile took t = 0.6 seconds to reach the top of the platform from its launching point, calculate the height of the platform, h. Use g = 9.8 m/s2 and retain 2 decimal places in your answer.

A projectile is launched from the top of a platform of height h = 0.3 meters, with velocity |v→| = 1 m/s, at an angle θ = 43 degrees from the horizontal direction. How much time (in seconds) will it take for the projectile to reach the ground below the platform? Retain 1 decimal place for your answer. Use g = 9.8 m/s2
