Answer 1

Answer:

13. A girl weighing 25 kg stands on the tloor. She exerts a downward force of 250 N on the floor. What force does the floor exert on her ? This is due to Newton's third law of motion which states that to every action there is an equal and opposite reaction.

11. Mass, m = 1 kg

Acceleration, a =

1m/s2

Force F = m x a = 1

x 1= 1N

14. Less mass of the small car makes it easier to accelerate a small car than a large car because acceleration is inversely proportional to mass of the car

Answer 2

Answer:

11. f=1N

f=ma

f=1×1

f=1
