<span>The fact that light travels at 300,000 km/s is a consequence of Energy Conservation
The particle that move with that kind of speed creates energy way faster than the particle that don't. Which means that it would require less effort to produce the energy,</span>

A ball of mass 2.0 kg falls vertically and hits the ground with speed 7.0 ms-1 as shown below.

Sauron [17]

Answer:

8.0 Ns

Explanation:

Change in momentum is given as:

Final momentum - Initial momentum

= m*v - m*u

Where m = mass of ball

v = final velocity

u = initial velocity

Change in momentum = (2.0 * 3.0) - (2.0 * 7.0)

= 6.0 - 14.0 = -8.0 Ns

The magnitude will be |-8.0| = 8.0 Ns

A 0.15 kg baseball is pushed with 100 N force. what will its acceleration be?

sammy [17]

Answer:

The acceleration of the ball is 666.67 m/s²

Explanation:

It is given that,

Mass of the baseball, m = 0.15 kg

Applied force to it, F = 100 N

We need to find the acceleration of the ball. It can be calculated using Newton's second law of motion as :

F = ma

$a=\dfrac{F}{m}$

$a=\dfrac{100\ N}{0.15\ kg}$

$a=666.67\ m/s^2$

So, the acceleration of the ball is 666.67 m/s². Hence, this is the required solution.
