Explanation:
The acceleration is equal to force divided by mass which would be 100 / 50 which is 2 m/s2
Answer:
7.5 m/s²
Explanation:
The following data were obtained from the question:
Initial velocity (u) = 21 m/s
Final velocity (v) = 36 m/s
Time (t) = 2 secs
Acceleration (a) =..?
The acceleration of an object is simply defined as the rate of change of velocity of the object with time. Mathematically, it is represented as:
Acceleration (a) = (final velocity (v) – initial velocity (u)) / time (t)
a = (v – u)/t
With the above formula, we can determine the acceleration of the roller coaster as follow:
a = (v – u)/t
a = (36 – 21)/2
a = 15/2
a = 7.5 m/s²
Therefore, the acceleration of the roller coaster is 7.5 m/s².
