d) 0 m/s
Explanation:
We need to apply the accelerated motion formulas.
The acceleration is given by:
we need to calculate the time the cheetah takes to stop when it starts to decelerate:
We need to calculate the displacement for all of the stages:
stage 1:
stage 2:
stage 3:
The total displacement is given by:
the final velocity of the cheetah is zero because the cheetah decelerates until stop.
A) The magnitude of the electric field generated by a single point charge is given by
where k is the Coulomb's constant, q is the charge and r is the distance at which we calculate the field.
Since we want to know the intensity of the field at distance of r=4.52 m from the charge of q=8.15 C, the intensity of the electric field is
b) Direction of the field
The charge that produces the field is negative, and we know that the electric field generated by a negative charge points toward the charge. Therefore, the direction of the electric field is towards the charge.
