It's B.
It's never going to be true UNLESS you cooled the entire thing to below zero then it could be true.
Answer:
22m/s
Explanation:
Step one:
Given data
Initial velocity of roller coster u= 6 m/s
Final velocity v= 72m/s
time t= 3 seconds
Required
We want to solve for the acceleration of the roller coster
Step two:
From the formula
acceleration= v-u/t
substitute
a= 72-6/3
a=66
/3
a= 22 m/s
The cars acceleration 22m/s
Picture 1 and 2 or am I wrong and it's not that obvious.
