Did you notice that equation next to the word "SPEED" up at the top, before question #1 ?

<em>Speed = (distance) / (time)</em>

All five of these questions are answered by using that same equation.  This is a big part of the reason why the equation is printed before these questions.

Every one of these 5 questions GIVES you a distance and a time, and you're supposed to find the speed.  EVERY ONE of them !

For each of these questions, take the distance, divide it by the time, and the quotient you get is the speed.

A 60.0 kg girl stands up on a stationary floating raft and decides to go into shore. She dives off the 180 kg floating raft with
lord [1]
Momentum, p = m.v
m of the girl = 60.0 kg
m of the boat = 180 kg
v of the girl = 4.0 m/s

A) Momentum of the girl as she is diving:
p = m.v = 60.0 kg * 4.0 m/s = 24.0 N/s

B) momentum of the raft = - momentum of the girl = -24.0 N/s

C) speed of the raft

p = m.v ; v = p/m = 24.0N/s / 180 kg = -0.13 m/s [i.e. in the opposite direction of the girl's velocity]

<h2>Answer:</h2>

<em>Hello, </em>

<h3><u>QUESTION)</u></h3>

According to the second Newton's Law,

<em>✔ We have : F = m x a ⇔ m = F/a </em>

  • m = 3000/15
  • m = 200 kg

The mass of the object is therefore 200 kg.
