Answer:
450 × 10 ⁻⁹ N
Explanation:
From the given:
The direction of force is;



Hence, the angle is 45° counterclockwise from + x-axis
However;
the magnitude of the force is:



Answer:
Below is the calculation of all the required quantities. From the calculations, Vx must change, the velocity before hitting the ground must change and the angles also must change.
Explanation:
Below is an attachment that contains the calculation steps.

Answer:
Explanation:
As an example, ice on steel has a low coefficient of friction – the two materials slide past each other easily – while rubber on pavement has a high coefficient of friction – the materials do not slide past each other easily. The coefficients of friction ranges from near 0 to greater than 1.
