However, at time t = 0, the pilot begins to fly over %3D ground sloping upward at angle 0 = 4.1° (see the figure). If the pilot does not change the airplane's heading, at what timet does the plane strike the ground? Number i Units
Here you are designing a motorcycle stunt where the motorcycle leaves a ramp at an angle θ and lands on another ramp of the same height. You need to know where to place the second ramp. You will make a mathema1cal model to predict the range (i.e., to predict how far the motorcycle will land from the first ramp).
Lesson: Projectiles When there is air resistance present how to the velocity and acceleration vectors behave? O The acceleration vector is perpendicular to the trajectory and the velocity vector is at a tangent to it. O The acceleration changes throughout the flight with its x-component opposite the direction of motion. The velocity vector is at a tangent to the trajectory O The acceleration vector is constant and points straight down. The velocity vector is at a tangent to the trajectory O The acceleration and velocity vectors are both constant magnitude but continually change direction.
