A projectile launched from the ground is aimed to hit a ground target 800 m away from the launch site. Q1: At what angle the projectile must be fired in order to hit the target in 2 s? Q2: Find the initial speed of the projectile.

Step 1
The horizontal and vertical displacements x and y of a projectile launched with an initial speed v0 at an angle θ from the horizontal are given by: x = v0 * t * cos(θ) y = v0 * t * sin(θ) - 0.5 * g * t^2 where g is the acceleration due to gravity (approximately Show more…

A projectile launched from the ground is aimed to hit a spot 1200 m away from the launch site. Q1: At what angle the projectile must be fired in order to hit the target in 2 s? Q2: Find the initial speed of the projectile. 3. A diver jumps off diving board into a deep pool. The diver's downward motion stops 3 m below the water surface. The deceleration of the diver while under water takes time 1 s. Q1: How high above the water's surface is the diving board?

Hitting a target You are launching a projectile horizontally from a height h. You intend to hit a target a horizontal distance L away. Throughout this problem you may neglect air resistance. 1. What speed should you launch the projectile at in order to hit the target? 2. At what speed will the projectile hit the target?
