Answer:

6m/s²

Explanation:

Given parameters:

Initial velocity  = 35m/s

Final velocity  = 65m/s

Time taken  = 5s

Unknown:

Acceleration = ?

Solution:

Acceleration is the rate of change of velocity with time taken;

   Acceleration  = \frac{Final velocity  - Initial velocity }{time}  

So;

 Acceleration   = \frac{65  - 35}{5}    = 6m/s²

a farmer lifts a bale of hay that is 12m off the ground . If he uses a force of 350 n, how much work does the farmer do?
hjlf

Answer:

4200 Joules

Explanation:

Work done =force x distance

From the question , we’re given f =350N ,

d = 12m

Using the above formula, we have

Workdone = 350 x 12

= 4200 Joules

Why is it important to know how fast a roller coaster travels at certain points on the track?
jolli1 [7]

It's important because you have to know when to make it go faster or else you might not be able to go upside down or in a circle

Weigt A box sitting still on the ground by itself has a weight of 700N, what is the mass? (gravity's acceleration is 9.80 m/s2)​
Alex
  • Force=700N
  • Acceleration=9.8m/s^2

Using newtons law

\\ \rm\longmapsto F=ma

\\ \rm\longmapsto m=\dfrac{F}{a}

\\ \rm\longmapsto m=\dfrac{700}{9.8}

\\ \rm\longmapsto m=71.4kg

Write a brief essay describing how Newton’s Laws explain how a rocket in space can move objects
statuscvo [17]
The First Law describes how an object acts when no force is acting upon it. So, rockets stay still until a force is applied to move them. Likewise, once they're in motion, they won't stop until a force is applied. Newton's Second Law tells us that the more mass an object has, the more force is needed to move it. A larger rocket will need stronger forces (eg. more fuel) to make it accelerate. The space shuttles required seven pounds of fuel for every pound of payload they carry. Newton's Third Law states that "every action has an equal and opposite reaction". In a rocket, burning fuel creates a push on the front of the rocket pushing it forward.
