Two identical 0.50-kg carts, each 0.10 m long, are at rest on a low-friction track and are connected by a spring that is initial
Keith_Richards [23]

Answer:

The system's kinetic energy changes by 3.6 J

Explanation:

The given parameters are;

The number of cart = 2

The mass of each cart = 0.5kg

The initial length of the spring = 0.50 m

The final length of the spring =T0.3 m

The change in position of the first cart = 0.6 m

The energy given to the first cart = Work done by the force = Force × Displacement

The initial kinetic energy of the two cart moving together = Energy given to the first cart = 6.0 × 0.2 = 1.2J

The kinetic energy given to the two cart combined = The applied force × The total displacement of the two cart as they move together

The kinetic energy given to the two cart combined = 6.0 × (0.6 - 0.2)

The kinetic energy given to the two cart combined = 6.0 × 0.4 = 2.4 J

The total kinetic energy given to the two cart = 1.2 + 2.4 = 3.6 J

The total kinetic energy given to the two cart = 3.6 J

The system's kinetic energy changes by 3.6 J.

If a person uses about 4 calories to fuel a minute of walking, and it takes about 20 minutes to walk a mile, approximately how m
Lemur [1.5K]

Answer:

43.75 miles must a person walk to utilize the energy in (“burn”) a pound of fat.

Explanation:

3,500 calories are present in 1 pound of the fat.

Thus, given that:

<u>4 calories are burnt in 1 minute of walking.</u>

So,

1 calories are burnt in 1/4 minute of walking.

Or,

<u>1 calories are burnt in 0.25 minute of walking.</u>

Thus,

<u>3500 calories are burnt in 0.25*3500 minutes of walking</u>

Minutes of walking needed to burn 3500 calories = 875 minutes.

Also, given that:

<u>20 minutes of walking covers 1 mile.</u>

<u>1 minute of walking covers 1/20 mile.</u>

So,

<u>875 minutes of walking covers (1/20)*875 mile.</u>

<u>43.75 miles must a person walk to utilize the energy in (“burn”) a pound of fat.</u>

A 1900kg airplane is flying at an altitude of 510 above the ground. What is the gravitational potential energy in Joules?
Natalija [7]

Answer: 9496200 joules

Explanation:

Gravitational potential energy, GPE is the energy possessed by the moving plane since it moves against gravity.

Thus, GPE = Mass m x Acceleration due to gravity g x Height h

Since Mass = 1900kg

g = 9.8m/s^2

h = 510 metres (units of height is metres)

Thus, GPE = 1900kg x 9.8m/s^2 x 510m

GPE = 9496200 joules

Thus, the gravitational potential energy of the airplane is 9496200 joules
