Force = (mass) x (acceleration) Newton's second law of motion.
Force = (2 kg) x (3 m/s²) = 6 newtons.
Newton´s thrid law of motion states that:
Every action has an equal and opposite reaction.
c. equal, opposite.
<h3>Answer</h3>
a. 8J
b. 90J
<h3>Notes formula</h3>
W = F × s
W = Work done (J)
F = Force (N)
s = distance (m)
<h3>Known that </h3>
a. F = 4N
s = 2m
b. F = 30N
s = 3m
<h3>Question</h3>
a. W = ..?
b. W = ..?
<h3>Way to do it</h3>
a. W = F × s
= 4N × 2m = 8J
b. W = F × s
= 30N × 3m = 90J

Answer:
25 m/s
Explanation:
Impulse = change in momentum
F Δt = m Δv
(3750 N) (0.5 s) = (75 kg) (v − 0 m/s)
v = 25 m/s
