A ball of mass [tex]0.60kg[/tex] rolls North at [tex]4.0ms^{-1}[/tex]. It meets a slope which causes a force of [tex]0.18N[/tex] East. This force lasts for [tex]10s[/tex]. Calculate the final velocity of the ball. Neglect any friction effects.

2. Relevant equations

[tex]F = m.a[/tex]

[tex]v = u+at[/tex]

3. The attempt at a solution

[tex]m = 0.60kg \ , \ v = 4.0ms^{-1} \ , \ F = 0.18N \ , \ t = 10s[/tex]

[tex]F = m.a[/tex]

[tex]a = \frac{F}{m} = \frac{0.18}{0.60} = 0.30ms^{-2}[/tex]

[tex]v = u + at[/tex]

[tex]v = 4.0 + 0.3 \times 10[/tex]

[tex]v = 12 ms^{-1}[/tex]

Where did I go wrong?
