You stand on top of a 45.0 m tall building and throw a ball straight up with a speed of 10.0 m/s. How long did the ball take to hit the ground below?
Added by Steve A.
Step 1
We know that the final velocity at the highest point is 0 m/s, the initial velocity is 10 m/s, and the acceleration due to gravity is -9.8 m/sĀ² (negative because it's acting downwards). We can use the equation of motion: final velocity = initial velocity + Show moreā¦

An airplane during horizontally with a speed of 50 km/h at a height of 1200 m drops 4 crates (see following figure). If the parachute fails to open, how far in front of the release point (in km) does the crate hit the ground? Assume that the acceleration due to gravity is 9.8 m/s^2.
