Question

A force of 40 N acts upon a 2 kg block. Calculate the acceleration of the object. *

20 m/s2

20 m/s

80 m/s2

80 m/s

​

Answer 1

Explanation:

Sounds like a job for Newton's second law.

In summary, this law of motion states that the acceleration of an object is proportional to, and in the same direction as, the net force acting on the object, as well as inversely proportional to the mass.

This gives the familiar equation:

→

F

net

=

m

→

a

We are given a force and a mass and we want an acceleration. We'll have to use a bit of algebra.

F

=

m

a

⇒

F

m

=

a

Given

F

=

40

N

and

m

=

5

kg

, we have:

a

=

40

N

5

kg

⇒

a

=

8

Answer 2

Given data is

F=$40 N$

m= $2 Kg$

find acceleration (a)

formula use F=ma

we have to find (a) so separate m (m) gets into the denominator of F we get

a=$\frac{F}{m}$

put the value

$a=\frac{40}{2}$

$a=20 m/s^2$

so the answer is $20m/s^2$.
