Answer:

Force / mass

Explanation:

Divide mass on both sides to get acceleration by itself leaving you with mass below force hence divide force by mass

Newton’s 2nd : Force = rate of change of momentum
= (mv - mu) / t
= m (v-u) / t
= m a

( since a = (v-u)/t )

From F = m a then a= F/m

A hammer falls off the top roof and strikes the ground with a certain kinetic energy. If it fell from a roof twice as tall how w
Akimi4 [234]

The kinetic energy with which the hammer strikes the ground
is exactly the potential energy it had at the height from which it fell. 

Potential energy is (mass) x (gravity) x (height) .... directly proportional
to height.

Starting from double the height, it starts with double the potential
energy, and it reaches the bottom with double the kinetic energy.

A proton is 0.9 meters away from a 1.4 C charge. What is the magnitude of the electric force between the proton and the charge
Digiron [165]

Answer:

F = 2.49 x 10⁻⁹ N

Explanation:

The electrostatic force between two charged bodies is given by Colomb's Law:

F = \frac{kq_1q_2}{r^2}\\

where,

F = Electrostatic Force = ?

k = colomb's constant = 9 x 10⁹ N.m²/C²

q₁ = charge on proton = 1.6 x 10⁻¹⁹ C

q₂ = second charge = 1.4 C

r = distace between charges = 0.9 m

Therefore,

F = \frac{(9\ x\ 10^9\ N.m^2/C^2)(1.6\ x\ 10^{-19}\ C)(1.4\ C)}{(0.9\ m)^2}

<u>F = 2.49 x 10⁻⁹ N</u>

The net torce on an object moving with constant speed in circular motion is in which direction?
aleksley [76]

The correct answer is C) towards the center of the circle.

Although the object is moving at a constant speed it is constantly accelerating due to the constant change in direction as it describes the circular path. This causes a constant change in velocity as velocity is a vector quantity.

For the object to maintain the circular path there has to be centripetal force acting on the object and this centripetal force is directed towards the center of the circle.
