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.
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.
a) How high will it go? b) What horizontal distance will the arrow travel? 3. A person kicks a rock off a cliff horizontally with a speed of 20 m/s. It takes 7.0 seconds to hit the ground, find: a) height of the cliff. b) final vertical velocity. c) range. A ship fires its guns with a speed of 400 m/s at an angle of 35° with the horizontal.
