Answer:
6.5 m
Explanation:
First of all, we need to compute the acceleration of the skier. We know that there is only force acting on the skier: the force of friction, which is in the opposite direction to the motion of the skier. Using 2nd Newton Law:
where is the force of friction, with
is the coefficient of kinetic friction
m is the mass of the skier
is the acceleration due to gravity
Re-arranging the equation, we find:
So now we can use the following SUVAT equation to calcualte the total displacement of the skier before stopping:
where
v = 0 is the final velocity
u = 5.30 m/s is the initial velocity
a = -2.16 m/s^2 is the acceleration
d = ? is the displacement
Solving the formula for d, we find:
Explanation:
The magnetic force acting on a charged particle when placed in a magnetic field is given by :
is the angle between v and B.
If means that if the angle between v and B is 0 degrees or both are acting in same direction, then magnetic force is equal to 0.
Here, a charge is moving in a magnetic field that points to the left. Hence, for a charge particle that experiences no magnetic force, the charge must move in the left direction such that they move parallel to each other.
