I think that the answer is latin
Tectonic plates under the ground ,either go on top of each other or crash.
Answer:
<em>The final velocity of the student and the boat is 1.66 m/s</em>
Explanation:
<u>Law Of Conservation Of Linear Momentum
</u>
The total momentum of a system of bodies is conserved unless an external force is applied to it. The formula for the momentum of a body with mass m and velocity v is P=mv. If we have a system of bodies, then the total momentum is the sum of them all
Let's call the mass of the physics student, the mass of the boat, the initial speed of the student, the initial speed of the boat, the final speed of both, assumed common since they keep joined after the jump. Applying the law of conservation of momentum, being the initial and final momentum of the system, we have
Solving for
The final velocity of the student and the boat is 1.66 m/s
To solve this problem we must resort to the definition of Normal Force, in which, it is the component of a contact force that is perpendicular to the surface that an object contacts.
where,
m=mass
g= Gravitational Acceleration
Normal force that the force exerts on the ladder is the weight of the ladder, then
F=mg
F=18*9.8
F=176.58N
Therefore normal force the floor exerts on the ladder is 176.58N
