A roller coaster approaches the top of a 37-meter hill traveling 2.5 m/s. The coaster descends the hill and travels up the next hill, which has a height of 17 m. Ignoring all aspects of friction and air resistance, determine the speed (in m/s) of the coaster at the top of the 17-meter hill.

where's the following? you gotta add it to know what the choices are

explanation:

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

a is the best answer your welcome

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
