Example 10-5 Consider the simple horizontal curve given in Example 10-1, with a tangent distance T= 229.27 ft and an arc length L 391.53 ft. If the station of the PI is established as 7 +47.64, find the stations of the PC and the PT
Relative Velocity and Projectile Motion . a)An airplane moves horizontally with a constant velocity VA/G 300m/s with respect to ground at height H = 600m. The plane fires a container, which has a speed VC/A = 300m/s and direction α = 300 with respect to the airplane immediately after the firing. The container performs a projectile motion and hits the ground at a horizontal distance L from the point of the firing (see figure a)What is the velocity (horizontal and...
A rock thrown with speed 7.00 m/s and launch angle 30.0 ∘ (above the horizontal) travels a horizontal distance of d = 16.0 m before hitting the ground. From what height was the rock thrown? Use the value g = 9.800 m/ s 2 for the free-fall acceleration.Find the height y i from which the rock was launched.
