Answer:

Balanced forces.

Explanation:

Forces that are opposite in direction, and, equal in size do not cause a change in motion or position are known as balanced forces. When it is applied to an object at rest, the object will not show any movement.

A good example of a balanced force is when we are trying to push a wall, the wall will push back with an opposite but equal force, so, this time neither the wall nor you will move.

Prove mathematically :<br>1. v = u + at<br>2. s = ut+1*2 at

aleksley [76]

Answer:

a.v=u+v/2

a.v=s/t

combining two equation we get,

u+v/2=s/t

(u+v)t/2=s

{u+(u+at)}t/2=s

(u+u+at)t/2=s

(2u+at)t/2=s

2ut+at^2/2=s

2ut/2+at^2/2=s

UT +1/2at^2=s

proved

a=v-u/t

at=v-u

u+at=v

Two steamrollers begin 105 mm apart and head toward each other, each at a constant speed of 1.20 m/s. At the same instant, a fly

levacccp [35]

Answer: 109.4 mm

Explanation: <u>Distance</u> is a scalar quantity and it is the measure of how much path there are between two locations. It can be calculated as the product of velocity and time: d = vt

The separation between the two steamrollers is 105 mm or 0.105 m. They collide to each other at the middle of the separation:

location of collision = $\frac{0.105}{2}$ = 0.0525 m
