A projectile is launched from ground level traveling at a speed of 28.6 m/s and at an angle of 27.6º above horizontal. Assume that air-resistance can be ignored. The projectile is launched toward a vertical wall that is a horizontal distance of 32.6 m from where the projectile is launched. How hig above the ground does the projectile strike the wall?

A projectile is fired at ?0=433.0 m/s at an angle of ?=69.0 with respect to the horizontal.   Assuming no air resistance, what is the range R of the projectile?

A ball is thrown at an angle of 30° from the top of a building 0.10 km high. The ball strikes the ground at a point 125 m horizontally away from and below the point of release. (a)What is the initial speed of the ball? (b) What is the speed of the ball just before it strikes the ground?

A catapult on a cliff launches a large round rock towards a ship on the ocean below. The rock leaves the catapult from a height H of 33.0 m above sea level, directed at an angle e above the horizontal with an unknown speed vo. The projectile remains in flight for 6.00 seconds and travels a horizontal distance D of 145.0 m. Assuming that air friction can be neglected, calculate the value of the angle 0. 55.299° You know how long the rock is in the air. This yields its horizontal velocity from the horizontal distance it travels. You get the vertical component of the velocity by using the equation of motion with constant acceleration. From the two velocity components you can figure out the angle. Incorrect. Tries 9/10 Previous Tries Submit Answer Calculate the speed at which the rock is launched. 34.93m/s You know the net change in height of the rock, along with the horizontal distance it travels. Since you calculated the initial angle already, you can use your equations of position in…
