C.) Friction.

Reason:
No force is opposing the motion of an object except frictional force. Hence an object requires 15 N of force to set an object in motion and is greater than friction. Hope this helps, have a great day ahead!

Answer:

(c). Friction

Explanation:

An object at rest requires a force of 15 newtons to set it into motion. this force is greater than friction force.

Friction force :

Friction is the force which opposes the motion of an object. It depends upon on the contacting surface.

When the applied force is greater than the frictional force then the object starts moving.

You run a race with your friend. At first you each have the same kinetic energy, but then you find that she is beating you. When

Blizzard [7]

Answer:

52.49 Kg

Explanation:

Let m1 and v1 denote your mass and velocity respectively

Let m2 and v2 denote your friends mass and velocity respectively

Kinetic energy is given by

$KE= 0.5mv^{2}$

Since your kinetic energies are the same hence

$0.5m1(v1)^{2}=0.5m2(v2)^{2}$

$m1(v1)^{2}=m2(v2)^{2}$ and making m2 the subject then

$m2=\frac { m1(v1)^{2}}{(v2)^{2}}$

Since v2 is v1+0.28v1=1.28v1

Substituting m1 for 86 Kg

$m2=\frac { 86 Kg(v1)^{2}}{(1.28v1)^{2}}= 52.49023\approx 52.49 Kg$
