Use the right equation. To calculate the normal force of an object at an angle, you need to use the formula: N = m * g * cos (x) For this equation, N refers to the normal force, m refers to the object's mass, g refers to the acceleration of gravity, and x refers to the angle of incline.
Answer:
The expected dynamic error is 0.019
The phase shift is -23.10°C
Explanation:
The explanation is shown on the first uploaded image
More force is needed for more mass. Therefore, if the mass is greater and the force is not enough then the object will less likely accelerate
Forces are exerted I believe : all of the above
The action force might be Tyler throwing the ball
I don't know the last one
