The resultant velocity is 360.81 m/s and the velocity of the dolphin swims is 11 m/s
Explanation:
The boat travelling is 13.4 m/s
The captain walks on the deck is 1.3 m/s
The resultant velocity = a² + b² = c²
= 13.4² + 1.3²
= 179.56 + 1.69
c² =
c= 360.81 m/s
To find the velocity, the dolphin swims in 55 m and the acceleration is 5.0 s
velocity = distance / acceleration
=
= 11 m/s
Therefore, the velocity is 11 m/s.
Answer:
C. Newton
Explanation:
Definition of newton: The SI unit of force. It is equal to the force that would give a mass of one kilogram an acceleration of one meter per second per second, and is equivalent to 100,000 dynes.

Answer:
6000 N
Explanation:
Newton's third law states that:
"When an object A exerts a force (called action) on an object B, then object B exerts an equal and opposite force (called reaction) on object A"
In this problem, we can identify:
- The truck as object A
- The car as object B
This means that if the force exerted by the truck on the car (the action) is 6000 N, then the force exerted by the car on the truck (the reaction) must also have equal magnitude, 6000 N, and be in the opposite direction.
