Calculate the velocity of the missile just before it hits the ground. If the missile hits the ground and bounces up at an angle of 30 with a speed of 200 m/s, how far away from the point of impact will it land? Solution: This is a projectile motion problem, a type of motion in which, without air resis-tance, we have ax = 0 and ay = −g.
Learn about projectile motion by firing various objects. Set parameters such as angle, initial speed, and mass. Explore vector representations, and add air resistance to investigate the factors that influence drag.
The trajectory of a projectile launched from ground is given by the equation y = -0.025 x 2 + 0.5 x, where x and y are the coordinate of the projectile on a rectangular system of axes. a) Find the initial velocity and the angle at which the projectile is launched.
So the formulas we want are: v_x_init = v*cos(theta*PI()/180), v_y_init = v*sin(theta*PI()/180). In A3 write: Projectile fired at speed v at angle theta degrees to horizontal. In A5 write v=, in A6 write theta=. Insert the corresponding names in B5 and B6. Now, in B8 and B9 write =v*cos(theta*PI()/180) and =v*sin(theta*PI()/180) respectively.
