The coefficient of static friction is 0.357 and the coefficient of kinetic friction is 0.265.
Explanation:
Coefficient of static friction is defined as the proportionality constant for the frictional force between the crate and floor for starting the motion of crate and normal force acting on the crate. As the normal force of the crate is equal to the influence of acceleration due to gravity acting on the mass of the crate, the frictional force for static friction coefficient will be the force applied to move the crate.
Thus,
Since, the static friction force is 70 N, the normal force is equal to
So normal force is 196 N and static force is 70 N, and the ratio of static friction force to the normal force will give the coefficient of static friction.
Similarly, the coefficient of kinetic friction can be determined from the ratio of kinetic friction force to normal force. Here the kinetic friction force will be equal to the force applied on the crate to keep it moving.
Thus, the coefficient of static friction is 0.357 and the coefficient of kinetic friction is 0.265.
Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.
So, the correct answer is C) is equal in speed and opposite in direction
By unplugging unused devices, by turning off any unused lights, and by switching your lightbulbs to something more energy efficient.

Determine Jupiter's velocity
First, we calculate the circumference (C) of Jupiter:
Substitute values for r and
Next, convert time to seconds:
The velocity is then calculated as:
m/s
<em>Hence, Jupiter's velocity is 1306.76m/s</em>
