<h3><u>Given</u><u>:</u><u>-</u></h3>

Velocity,v = 16 m/s

Kinetic energy = 1892 J

<h3><u>To</u><u> </u><u>be</u><u> </u><u>calculated:-</u><u> </u></h3>

Calculate the mass of the stone.

<h3><u>Formula</u><u> </u><u>used:-</u><u> </u></h3>

Kinetic energy = 1/2 × m × v²

<h3><u>Solution:-</u><u> </u></h3>

We know that,

Kinetic energy = 1/2 × m × v²

⇒ 1892 = 1/2 × m × ( 16 )²

⇒ 1892 = 1/2 × m × 256

⇒ 1892 = 128m

⇒ m = 1892/128

⇒ m = 14.78 kg

A constant force is applied to an object, causing the object to accelerate at 10 m/s^2. What will the acceleration be if: a) The

Liula [17]

What you need to know is that the force is

F=ma

The force is the product of mass and acceleration

this means that the acceleration is

a=F/m

a) The force is halved?
this means that f will be $\frac{F}{2}$ now:

a= $\frac{F}{2m}$

So the accelaration will also he halved (it's the original acceleratation divided by 2)

b) The object's mass is halved?
a= $\frac{F}{m/2}$ =a= $\frac{F2}{m}$

which is the original acceleration times two!! so it will double

c) The force and the object's mass are both halved?
now we have

a= $\frac{F/2}{m/2}$ =a= $\frac{2F}{2m}$ =a= $\frac{F}{m}$

so they will cancel each other out and the acceleration will stay the same!
