3 a A motorcyclist starts from rest and reaches

The acceleration of the body is 2 m/s^2 while the deceleration is - 1.2 m/s^2.

<h3>What is the acceleration?</h3>

Let us recall that the acceleration is the change in the speed of a body with time. We have been told that the body accelerates for 3s and then decelerates to 2s. This implies that the total time that the object spent in motion is 5 s.

Thus;

v = u + at

v = final velocity

u = initial velocity

a = acceleration

t = time taken

v - u/t = a

a = 6 - 0/3

= 2 m/s^2

Again;

v - u/t = a

a = 0 - 6/5

a = - 1.2m/s^2

If kinetic energy of a body of mass 10 kg is 2000 J find velocity

weqwewe [10]

Answer:

I guess answer is 10m/s.

Explanation:

Kinetic Energy=1/2 mv^2

or,2000J=1/2×10kg×v^2

or2000J=5kg.v^2

or,2000J/5kg=v^2

or,100J/kg=v^2

or,v=10m/s

A circuit is shown in the picture above. The chemical energy in the battery is used to light up the light bulb on the other end.

Ainat [17]

To be honest, the picture is so far above that I can't see it at all.
But reading the information in the question's statement, I'd say
the blank should be filled in so that it says:

<span> The chemical energy in the battery is used to light up the light bulb
on the other end. Chemical energy in the battery is transformed into
electrical energy which runs through the circuit wire. (A)</span>
