make sure 100%

A projectile is fired from an elevation of 10 meters and lands a non-zero horizontal distance away at an elevation that is also 10 meters. The projectile has an initial velocity magnitude of 12 m/s. What two launch angles will yield a horizontal distance of 10.2 meters?

22° and 44°
22° and 68°
44° and 68°
44° and 88°
34° and 68°
44° and 46°

A projectile is fired from the ground (you can assume the initial height is the same as the ground) in a field so there are no obstacles in its way. The same projectile was then fired in the same way toward a wall that is a horizontal distance (d) m from where the projectile was fired, and the projectile (as it's going down) hit the wall. If the wall were slightly farther from where the projectile was launched (the projectile...

Basic Physics: Projectile Motion. 1. Given that a ball is launched perfectly horizontally from a height of 1.2 meters, and lands on the floor a horizontal distance of 2.6 meters away, find the initial speed (or "muzzle velocity") of the ball in meters per second. Use 9.82 meters per second for "g". 2. A ball is launched at an angle of 56.5 degrees up from the horizontal, with a muzzle velocity of 7 meters per second, from a launch point...

A projectile of mass 2.0 kg is fired in the air at an angle of 43.0° to the horizon at a speed of 44.0 m/s. At the highest point in its flight, the projectile breaks into three parts of mass 1.0 kg, 0.7 kg, and 0.3 kg. The 1.0 kg part falls straight down after breakup with an initial speed of 14.8 m/s, the 0.7 kg part moves in the original forward direction, and the 0.3 kg part goes straight...

A projectile is fired (by remote actuator) from a large flywheel supported on its axle by a stand of height h=25m. The flywheel has radius R= 20m; it spins with a period of revolution p=5s. Adam decides to release a ball at the very top of the rotation, so that its velocity is horizontal. What is the initial speed v of the ball, just as Adam releases it? How long is the ball in flight? When the ball lands, how...
