Question #e6bcc
1 Answer
Explanation:
We can use a kinematics equation to solve this...
Note: This roller coaster's acceleration is NOT
#-g# , as it is not falling freely. Instead, it's traveling down a slope, and the acceleration of this coaster is assumed to be constant, which also implies the slope is constant..
Aside from that, we can find the distance
We know:
-
the velocity
#v_x# at time#t# is#22# #"m/s"# -
the initial velocity
#v_(0x)# here is#4# #"m/s"# -
the time
#t# is#3# #"s"#
Plugging in the known values, we have
Therefore, if the acceleration of the roller coaster is constant down the slope, it will have traveled a distance of
