A block of weight w sits on a frictionless inclined plane, which makes an angle theta with respect to the horizontal, as shown.

A force of magnitude F applied parallel to the incline, pulls the block up the plane at constant speed. The block moves a distance L up the incline. The block does not stop after moving this distance but continues to move with constant speed. What is the total work Wtot done on the block by all forces? (Include only the work done after the block has started moving, not the work needed to start the block moving from rest.) What is Wg , the work done on the block by the force of gravity as the block moves a distance L up the incline? What is Wf the work done on the block by the applied force F as the block moves a distance L up the incline? What is Wnormal , the work done on the block by the normal force as the block moves a distance L up the inclined plane?

Calculate the energy that 1.5 kg of mass contains
Vsevolod [243]

Answer:

4.5(10)^8 joules

Explanation:

Mass–energy equivalence is the principle that says that anything that has mass has an equivalent amount of energy. Converse is also true.

The relation between energy and mass is given by E=mc^2

Here, E denotes energy, m denotes mass and c denotes speed of light

Mass (m)=1.5\,\,kg

Speed of light (c) = 3 × 10^8 m/s

Therefore,

E=1.5(3)(10)^8=4.5(10)^8  joules.

The S.I. unit of energy is joules which is equal to 1\,\,kg\,\,m^2/s^2

A carton is given a push across a horizontal, frictionless surface. The carton has a mass m, the push gives it an initial speed
sammy [17]

Answer and Explanation:

Data provided in the question

Carbon mass = m

Initial speed = v_i

Coefficient = μk

Based on the above information, the expressions are as follows

a. By using the energy considerations the expression for the carton moving distance is

As we know that

Fd = \frac{1}{2} m (v_i^2- v_f^2)

where,

v_f = 0

F = u_kmg

(\mu_kg) d = \frac{1}{2} m v_i^2

d = \frac{\frac{1}{2}v_i^2}{\mu_kg}

d = \frac{v_i^2}{2 \mu_kg}

b. The initial speed of the carton if the factor of 3 risen, so the expression is

v_i^1 = 3v_i

d^i = \frac{(3v_i^2)}{2\mu_kg}

= \frac{9v_i^2}{2\mu_kg}

d^i = 9(d)

A small boy is playing with a ball on a stationary train. If he places the ball on the floor of the train, when the train starts
expeople1 [14]

A small boy is playing with a ball on a stationary train. If he places the ball on the floor of the train, when the train starts moving the ball moves toward the back of the train. This happened due to inertia

An object at rest remains at rest, or if in motion, remains in motion unless a net external force acts on it .  

When a train starts moving forward, the ball placed on the floor  tends to fall backward is an example of inertia of rest. Due to the reason that the lower part of the ball is in contact with the surface and rest of the part is not . As the train starts moving, its lower part gets the motion as the floor starts moving but the upper part will remain as it is as it is not in contact with the floor , hence do not attain any motion due to the inertia of rest simultaneously i.e. it tends to remain at the same place.
