The millersburg ferry (m = 13000.0 kg loaded) is travelling at 11 m/s when the engines are put in reverse. the engineproduces a force of 1.0 x 106n for a period of 20.0 seconds.
a)what is the magnitude of the impulse from the engine?
b)what is the new momentum of the ferry? c)what is the new velocity of the ferry?

Explanation:

It is given that,

Mass of Millersburg Ferry, m = 13000 kg

Velocity, v = 11 m/s

Applied force, F = 10⁶ N

Time period, t = 20 seconds

(a) Impulse is given by the product of force and time taken i.e.

(b) Impulse is also given by the change in momentum i.e.

(c) For new velocity,

Hence, this is the required solution.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
