Use the impulse-momentum theorem to find how long a stone falling straight down takes to increase its speed from 5.6 m/s to 10.6 m/s . express your answer in seconds.

As stated, the impulse and momentum definitions will be used to later find the value of time through the force of gravity. According to the theory, the impulse formula is given as,

Here,

F = Force

Change in time

Now using the impulse theorem we have that,

Change in Impulse = Change in momentum

(1)

The change in momentum is given as

The force due to gravity is through the Newton's second law

Here,

m = mass

g = Acceleration due to gravity

Substitute the value in (1)

Therefore it will take 0.51s.

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
