Answer:

Scientists should perform experiment because Without them, things would most likely not be as perfect as they are now. They wouldn't work properly or they would have malfunctions. It is important to perform them because it makes things safer to use and it makes them more appealing because they work good and are not broken.

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.
