Steven carefully places a m = 1.85 kg wooden block on a frictionless ramp so that the block begins to slide down the ramp from r

est. The ramp makes an angle of θ = 51.3 ° up from the horizontal. Which forces do nonzero work on the block as it slides down the ramp?

Answer:

Gravity force

Explanation:

We are given that

Mass of wooden block,m=1.85 kg

\theta=51.3^{\circ}

We have to find the force which do non zero work on the block as it slides down the ramp.

When a block slides down the ramp on a frictionless surface .

Then, weight act on the wooden block in downward direction.

We know that weight is that force which act on the body due to gravity.

Then, we can say that the force which do nonzero work on the block as it slides down the ramp is gravity force.

James accelerates his skate board uniformly along a straight road from rest to 10 m/s in 4 seconds. What is James Acceleration?
lawyer [7]

Given:

u(initial velocity)=0

v(final velocity)= 10 m/s

t= 4 sec

Now we know that

v= u + at

Where v is the final velocity

u is the initial velocity

a is the acceleration measured in m/s^2

t is the time measured in sec

10=0+ax4

a=10/4

a=2.5 m/s^2

When the force acting on the body equal to acceleration?
topjm [15]

Answer:

Acceleration and velocity Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force.

If no friction acts on a diver during a dive, then which of the following statements is true? A) The total mechanical energy of
EleoNora [17]
If no frictional work is considered, then the energy of the system (the driver at all positions is conserved.

Let
position 1 = initial height of the diver (h₁), together with the initial velocity (v₁).
position 2 = final height of the diver (h₂) and the final velocity (v₂).

The initial PE = mgh₁ and the initial KE  = (1/2)mv₁²
where g = acceleration due to gravity,
m = mass of the diver.
Similarly, the final PE and KE are respectively mgh₂ and (1/2)mv₂².
PE in position 1 is converted into KE due to the loss in height from position 1 to position 2.
 
Therefore
(KE + PE) ₁ = (KE + PE)₂

Evaluate the given answers.
A) The total mechanical energy of the system increases.
     FALSE

B) Potential energy can be converted into kinetic energy but not vice versa.
     TRUE

C) (KE + PE)beginning = (KE + PE) end.
     TRUE

D) All of the above.
     FALSE
