Answer:
Structure and consistency
Answer: 8 m/s²
Explanation:
v₀ = initial velocity of the roller coaster at the top of hill = 10 m/s
v = final velocity of the roller coaster at the bottom of hill = 26 m/s
a = acceleration of the coaster = ?
t = time of travel = 2 sec
using the kinematics equation
v = v₀ + a t
inserting the values
26 = 10 + a (2)
subtracting 10 both side
26 - 10 = 10 - 10 + 2 a
16 = 2 a
dividing both side by "2"
16/2 = 2a/2
ans: 8 m/s²
