Answer:
p = mv, where p is momentum, m is mass, and v is velocity.
a. ) m = 12kg v = 14m/s
Momentum (p) = mv
= 12kg × 14m/s
= 168kg•m/s
b.) momentum (p) = 35 kg•m/s
velocity = 3m/s
p = mv
make m the subject
divide both sides by v
we get
m = p/v
Therefore m is
m = 35 kg•m/s / 3m/s
m = 11.67kg
Therefore the mass of the object is 11.67kg
Hope this helps
So we want to know what is the purpose of a lanyard attached to a safety switch. So in case the operator falls overboard a safety switch is installed and connected to the operators hand or waist. Which ever is more practical. This safety switch turns off the motor.
Answer:
The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases
