Newton's second law says that the acceleration of an object is produced by the force exerted on it.
Having this in mind, if you hit a baseball with a bat it will <u>accelerate according to the applied force.</u>

A 150kg person stands on a compression spring with spring constant 10, 000 N/m and norminal.Length of 0.50.What is the togal len

Eva8 [605]

Answer:

Total length of spring 0.647 m

Explanation:

We have given mass of the person m = 150 kg

Acceleration due to gravity $g=9.8m/sec^2$

Spring constant k = 10000 N/m

Nominal length of spring = 0.50

According to hook's law

$mg=kx$

$150\times 9.8=10000\times x$

x = 0.147 m

So total length of spring = 0.50+0.147 = 0.647 m

Suppose you look at the huge clock on the Big Ben Tower in London and it reads 12 noon. If you could travel away from the clock

spin [16.1K]

Answer:

Option C. be frozen at 12 noon

Explanation:

This can be explained by the special theory of relativity according to which at greater speeds time slows down and length contracts in the direction of motion.

Also if a body travels at the speed of light time will stop and the body will will reduce to zero length.

Therefore, for the given case time will freeze at 12 noon.
