Question

A 16.0 kg mass rests on a frictionless floor. If a 48.0 N force acts on it, how far will it slide in
2.50 s.

Answer 1

Answer:

force = mass x acceleration

48 N = 16 x a

a = 3 m/s2

now u = 0

t = 2.50s

then v = 0 + 3 x 2.5

7.5 m/s

hope this helps love

have a nice day

Answer 2

Concept Introduction:

The word "force" has a specific meaning in science. At this level, calling a force a push or even a pull is entirely appropriate. A force is not something an object "has in it" or that it "contains." One thing experiences a force from another. There are both living things and non-living objects in the concept of a force.

Given, $16.0 kg$ mass rests on a frictionless floor.

To find, how far will it slide in $2.50 s$.

Solution:

According to the question,

force = mass x acceleration

$48 N = 16 a$

$a = 3 m/s$²

Now $u = 0$

$t = 2.50s$

then, $v = 0 + 3$×$2.5$

$7.5 m/s$

Final Answer:

The final answer is $7.5 m/s$.
