A force of 100 newtons is applied to a box at an angle of 36º with the horizontal. If the mass of the box is 25 kilograms, what

notka56 [123]

Answer:

$a_x=4.944m/s^2$

Explanation:

Hello,

Based on the acting force that is applied horizontally, one can propose the following equation based on Newton's laws:

$F=ma$

Nevertheless, since we've got a angled force, it becomes:

$F=macos\theta$

In this case, $cos\theta$ accounts for the formed angle, so the horizontal acceleration turns out into:

$a_x=\frac{F}{mcos\theta}=\frac{100kg*\frac{m}{s^2} }{25kgcos(36^0)}=4.944m/s^2$

Best regads.
