What acceleration will you give to a 25kg box if you push it with a force of 85N

Physics

Grace [21]3 years ago

<h3>Answer:</h3>

3.4 m/s²

<h3>Explanation:</h3>

We are given;

  • Mass of the box as 25 kg
  • Force is 85 N

We are required to determine the acceleration;

  • According to second newton's law of motion force is given by the product of mass and acceleration.
  • That is;

Force = ma

Rearranging the formula;

a = F ÷ m

Therefore;

acceleration = 85 N ÷ 25 kg

                       = 3.4 m/s²

Thus, the acceleration of the box will be 3.4 m/s²

9. A 227 kg object is moved a distance of 2.4 m forward by a force. If 686 J of work is done on the object, what is the object’s
Korolek [52]

<em>1</em><em>.</em><em>259ms^2</em>

Explanation:

since, WORK DONE = FORCE*DISTANCE

AND, FORCE=MASS*ACCELERATION

SO, THE WORK DONE BECOMES=MASS*ACCELERATION*DISTANCE

ACCELERATION=WORK/(MASS*DISTANCE)

AND, WORK=686J

MASS=227kg

DISTANCE=2.4m

THEREFORE, ACCELERATION=686/(227*2.4)

=686/544.8

=1.259ms^2

1- A train travels 92 kilometers in 3 hours, and then 55 kilometers in 3 hours. What is its average speed?
Hunter-Best [27]
<h3>Answer:</h3>
  1. 24.5 km/h
  2. 4 17/27 m/s
  3. 11/3 m/s²
<h3>Explanation:</h3>

1. The average speed is the ratio of total distance to total time:

... speed = distance/time = (92 km +55 km)/(3 h +3h) = (147 km)/(6 h)

... = 24.5 km/h

2. speed = distance/time = (125 m)/(27 s) = 4 17/27 m/s

3. a = ∆v/∆t = (15 m/s -4 m/s)/(3 s) = 11/3 m/s²
