3 0

Answer:

70 kg man

Explanation:

Let their velocities be v

Mass of the man= 70 kg

Hence, momentum of the man= 70v

Mass of the boy= 40 kg

Hence, momentum of the boy= 40v

70v > 40v

Clearly the momentum of the man is greater than that of the boy.

A person kicks a 4.0-kilogram door with a 48-newton force causing the door to accelerate at 12 meters per second squared. What i
inna [77]

Answer:

-48 N

Explanation:

mass of door (m) = 4 kg

acceleration of the door = 12 m/s^{2}

force exerted by the person = 48 N

From Newton's third law of motion, action and reaction are equal but opposite. Therefore the force exerted on the door by the person which is 48 N will be the same as the force exerted on the person by the door but opposite in its direction, and this would be - 48 N

Infer the direction of the net force acting on a car as it slows down and turns right.
Kobotan [32]
Net force would be towards the right and back (opposite direction of motion) since it's slowing down (decelerating) and turning right.
