Answer:
Inertia : a property of matter by which it continue in its existing state of rest or uniform motion in a straight line, unless that state is changed by external force.

Answer:
The amount of potential energy that was initially stored in the spring is 88.8 J.
Explanation:
Given that,
Mass of block = 1.60 kg
Angle = 30.0°
Distance = 6.55 m
Speed = 7.50 m/s
Coefficient of kinetic friction = 0.50
We need to calculate the amount of potential energy
Using formula of conservation of energy between point A and B
Put the value into the formula
Hence, The amount of potential energy that was initially stored in the spring is 88.8 J.
Answer:
10.16 minutes
Explanation:
14 min 34.56 s = 14*60 + 34.56 = 874.56 seconds
The speed of record swimming is distance over time
v = 1500 / 874.56 = 1.715 m/s
0.65 miles = 0.65 * 1609 = 1045.85 m
The time it takes to swim 0.65 miles (1045.85 m) at the rate of 1.715 m/s is
t = s/v = 1045.85 / 1.715 = 609.77 s or 609.77 / 60 = 10.16 minutes
