Impulse is equal to change in momentum of an object. The only way to change an object's momentum is to apply a force for certain amount of time.
Impulse is calculated as follows: Δp = F * t
Put your values in the right spots and solve for F. In this case since F is multiplied by Time, you will divide both sides by the time to find your answer.
I’m trying to get my points up I have the same question
Answer:
A) After the Space Age ended, many people moved to other states and the economy began to decline.
Explanation:
After the space age ended, businesses slumped, when the space shuttle program ended those made redundant could not be re absorbed due to a lack of follow-on by NASA. The 2008 recession also had impacted businesses in the area. As such many moved to other states, which had the effect of a brain drain.
After Apollo, in the late 70's, there was a similar decline of economic activities as workers were laid off and where finding it hard to sell off their properties as the real estate prices where low.
All you need to know is that velocity is the derivative with respect to time of position.
Therefore: ds/dt = -32t +10
To know the velocity at t=2s you just need to plug t=2 for t in the equation above.
