Answer:
625 N
Explanation:
The impulse given to the nail is equal to the change in momentum of the hammer:
where
F is the force exerted by the hammer
is the time of contact
is the mass
is the change in velocity of the hammer
Substituting the data and re-arranging the equation, we can find the force:
Answer:
I say vehicle one, because both will apply the same amount of force but, because vehicle two has less mass, it will accelerate more rather than vehicle one which will accelerate less.
Answer:
C. Parallel
Explanation:
The resultant force is the sum of all forces acting on an object. This force results in an acceleration in the direction of the force, as described by Newton's second law.
∑F = ma
Explanation:
To be accurate, it must be able to make measurements that are close to the actual value.
