[tex]\tt{\huge{\blue{Explanation:}}}[/tex]
The force acting on an object is given by
[tex]\boxed{F = ma}[/tex]
where:
F = force
m = mass
a = acceleration
[tex]\tt{\huge{\red{Solution:}}}[/tex]
Solving for a
[tex]a = \dfrac{v_{f} - v_{i}}{t}[/tex]
[tex]a = \dfrac{\text{15 m/s} - \text{10 m/s}}{\text{25 s}}[/tex]
a = 0.2 m/s²
Solving for F
F = ma
F = (8 kg)(0.2 m/s²)
[tex]\boxed{F = \text{1.6 N}}[/tex]
Therefore, the force needed is 1.6 N.
