of mass
1.7 x 10^3 kilograms by 4.75 meters/second^2?
A. 3.6 x 102 newtons
B. 1.7 x 103 newtons
C. 8.1 x 103 newtons
D. 9.0 x 103 newtons​

Respuesta :

Answer:

8.71 x 10^3N - C

Step-by-step explanation:

Force = mass x acceleration

mass = 1.7 x 10^3 and acceleration = 4.75m/s^2

Force = 1.7 x 10^3 x 4.75 = 8075N = 8.71 x 10^3N

Answer:

8,075N

Step-by-step explanation:

The information we have is:

Mass:

[tex]m=1.7x10^3kg[/tex]

Acceleration:

[tex]a=4.75m/s^2[/tex]

We are asked to find the force that is necessary to create that acceleration in the given mass.

For this we use the equation of Newton's second law:

[tex]F=ma[/tex]

and now we susbtitute all the values into the equation to find the force [tex]F[/tex]:

[tex]F=(1.7x10^3kg)(4.75m/s^2)\\F=8,075N[/tex]

The magnitude of the force required is 8,075N
