A student fires a cannonball horizontally with a speed of 38.0m/s from the top of a building. The cannonball remains in the air for 2.70s. Neglect drag.
From what height was the cannonball launched?
How far from from the base of the building will the ball land (measured along the
ground)?

An astronaut floating in space is trying to use her jetpack to get back to her space station, but she is being pulled away by a nearby planet, as shown in the image below. her jetpack provides a constant thrust of 310 n. if she angles her jetpack in such a way that it cancels out the vertical force due to the planet's gravity, what is her net horizontal force? thaud 487 o a. 54.8 n toward the space station o b. 212.9 n toward the space station o c. 185.2 n toward the space station o d 956 n toward the space station
