Task:

If there is no friction between a block of mass $70\mathrm{kg}$ and the surface, what is the acceleration of block 1, a?. Enter your answer in $\mathrm{m} / \mathrm{s}^2$

Solution:

If motion on horizontal surface, then:

$$F \cos \theta = m a \Rightarrow a = \frac {F \cos \theta}{m} = \frac {F \cos \theta}{7 0} \left[ \frac {m}{s ^ {2}} \right].$$

Answer: $a = \frac{F\cos\theta}{70} (m / s^2)$
