Answer:
K.E = 30,000 J
Explanation:
Given,
The potential energy of the roller coaster car, P.E = 40000 J
The kinetic energy at height h/4, K.E = ?
According to the law of conservation of energy, the total energy of the system is conserved.
At height 'h', the total energy is,
P.E = mgh
K.E = 0
At height 'h/4', the total energy is
P.E + K.E = mgh
P.E = mgh/4
K.E = 1/2 mv²
Therefore,
mgh/4 + 1/2 mv² = mgh
gh/4 + v²/2 = gh
Hence,
v² = 3gh/2
Substituting in the K.E equation
K.E = 1/2 mv²
= 1/2 m (3gh/2)
= 3/4 mgh
= 3/4 x 40000
= 30000 J
Hence, the K.E of the roller coaster car is, K.E = 30000 J

Answer: 56994 miles
Explanation:
Given : Toby's Trucking Company determined that on an annual basis, the distance traveled per truck is normally distributed with

Standard deviation : 
Let a be the distance traveled by at least 72% of the trucks.
Let X be the random variable that represents the distance traveled by a truck
Then 
The critical value corresponds to p-value 0.72 :
Also, 

Hence, 56994 miles will be traveled by at least (equal to and more than) 72% of the trucks .
