We shall apply length contraction einstein's relativistic formula to calculate the length observed by observer on the earth . For the observer , increased length will be observed for an observer on the earth

$L=\frac{.5}{\sqrt{1-(\frac{.97c}{c})^2 } }$

$L=\frac{.5}{.24}$

L= 2.05

The length will appear to be 2.05 m . and width will appear to be .5 m to the observer on the spaceship. . It is so because it is length which is moving parallel to the direction of travel. Width will remain unchanged.

How do I calculate how many meters are in 7.2 light years?

Vikentia [17]

Answer:

68.2 Quadrillion meters

Explanation:

A lightyear is the distance that light travels in one year.

Speed of light is $3*10^8\ m/s$

So light covers 300,000,000 meters in one second.

One year has 31536000 seconds so , light covers

$9.461*10^{15}\ meters\ in\ one\ year$

so 7.2 light years is

$7.2*(9.461*10^{15})\\6.82*10^{16}$

so 7.2 light years is

6.82 x 10^(16) meters or

68.2 Quadrillion meters

A 0.80-kg soccer ball experinces an impulse of 25 N x s . Determine the momentum change of the soccer ball.

borishaifa [10]

If the impulse is 25 N-s, then so is the change in momentum.
The mass of the ball is extra, unneeded information.

Just to make sure, we can check out the units:

Momentum = (mass) x (speed) = kg-meter / sec

Impulse = (force) x (time) = (kg-meter / sec²) x (sec) = kg-meter / sec
