Answer:
The answer to your question is: Ep = 14715 Joules
Explanation:
Data
mass = 50 kg
Potential energy = ?
height = 30 m
g = 9.81 m/s²
Equation
Ep = mgh
Substitution
Ep = (50)(9.81)(30)
Ep = 14715 Joules
Answer:
25.71486 seconds
Explanation:
t = Time taken
u = Initial velocity = 60 mph
v = Final velocity = 80 mph
s = Displacement = 0.5 mile
a = Acceleration
Converting to m/s


From equation of motion


Time taken is 25.71486 seconds
