A toy car has a kinetic energy of 8 J. What is its kinetic energy after a frictional force of 0.5 N has acted on it for 6 m?
Nezavi [6.7K]

Answer:

Final kinetic energy, KE_f=5\ J  

Explanation:

It is given that,

Kinetic energy of toy car, KE_i = 8\ J

Frictional force, F = 0.5 N

Distance, d = 6 m

We need to find the kinetic energy after this frictional force has acted on it. We know that frictional force is an opposing force. The work done by the toy car is given by :

W=F\times d

W=-0.5\ N\times 6\ m

W = -3 J

We know that the work done is equal to the change in kinetic energy. Let KE_f is the final kinetic energy.

W=KE_f-KE_i

-3=KE_f-8

KE_f=5\ J

So, the final kinetic energy is the toy car is 5 J. Hence, this is the required solution.

Once carbon begins burning in the core of a high-mass star, the outer layers begin to fall inward, driving up the fusion rates a
sammy [17]

Answer:

Fusion rates and star evolution increase rapidly because of the conversion of hydrogen molecules to helium.

Explanation:

At the early stage of a star mass, hydrogen atoms are produced. After a few billion years, these hydrogen atoms formed at the core of the star mass begin to fuse on the external side of the core. Hydrogen atoms get rapidly fused, resulting to a contraction of the star core, and as more hydrogen atoms get fused, helium atoms are formed.

This action results into rapid into a rapid and violent burning action of hydrogen atoms around the core.

To understand the meaning and possible applications of the work-energy theorem.
rosijanka [135]

Answer:

   <u> a = V final 2___v initial2</u>

                      28

Explanation:

By definition for contant acceleration        <u>a =   V final ___v initial</u>

                                                                                      t

Furthermore the average speed is           <u>V abg =  v initial +v final</u>

                                                                                         2

Combine these relationships to eliminate t.               8 = Vabg t.

A deer is running from a mountain lion when it encounters a fence that is 1.50 m high. Seeing the fence, the deer jumps, leaving
Novosadov [1.4K]

Answer:

Explanation:

Given

Initial Velocity (u)=13 m/s

angle=29^{\circ}

distance between fence and deer=2.5 m

We consider deer jump similar to projectile motion

equation of trajectory

y=xtan\theta -\frac{gx^2}{2u^2(cos\theta )^2}

y=2.5tan(29)-\frac{9.8\times 2.5^2}{2\times 13^2\times (cos29)^2}

y=1.385-0.2368=1.148 m

Thus deer will cross the fence with an difference in its jump and fence

1.5-1.148=0.351 m

h_{max}=\frac{u^2sin^2\theta }{2g}

h_{max}=\frac{13^2\times (sin29)^2}{2\times 9.8}

h_{max}=2.02 m

so deer rises during when it is over fence
