It should be an Electrical conductor, since conductors allow for movement of electrons from one point to another.
Answer:
Aim directly at the monkey
Explanation:
Despite the mass differences, both the monkey and the food will experience the same acceleration hence while the food follows a projectile path, it will then fall and hit the monkey hence achieving the aim of feeding it. You don't need to aim below or above, aim it directly.
The mass slows to a rest from an initial speed of 10.0 m/s in a matter of 1.50 s. If we assume constant acceleration, then the mass has acceleration a such that
0 = 10.0 m/s + a (1.50 s) ⇒ a ≈ -(10.0 m/s)/(1.50 s)
The net force acting on the mass as it slows down is
∑ F[horizontal] = -F[friction] = ma
where m = 15.0 kg, and we take the direction in which friction is acting to be negative. Then
-F[friction] = -(15.0 kg) (10.0 m/s)/(1.50 s) ⇒ F[friction] = 100 N
Force is the interaction that changes the motion of an object. If we want to make a jump, our legs have to exert a force to the ground (or launch points), so that we can gain an equal and opposite force that changes our motion from being static on the ground to moving forward.
