Answer:

9.14x10^22J

Explanation:

r= 1/√1-(0.17c)²/c²

1.01477

E= rmc²

9.14*10^22J

A ferry is travelling at 10 m/s relative to the river towards the south. The river is flowing at 2 m/s relative to
mixer [17]

Answer:

11 m/s south

Explanation:

The velocity of the passenger relative to the river bank is equal to the velocity of the passenger relative to the ferry, plus the velocity of the ferry relative to the river, plus the velocity of the river relative to the river bank.

v_passenger,bank = v_passenger,ferry + v_ferry,river + v_river,bank

If we take north to be positive and south to be negative:

v = 1.0 m/s + (-10 m/s) + (-2 m/s)

v = -11 m/s

v = 11 m/s south

If you increase the force acting on an object, what will happen to the object's motion
Mama L [17]
Force is directly proportional to rate of change of velocity so it increasing, velocity (motion of the object) will also increase.

a model rocket climbs 200 m in 4 seconds. if was moving 10 m/s to begin with, what is it’s final velocity?
artcher [175]
So first Identify all the given Varibales so u can choose which Eqauton to use

D=200m
T=4s
Vi=10m/s
Vf=?

You should this equation

D= 0.50(Vf+Vi)T

Plug in the values

200= 0.50 (Vf+10) 4

Divide the 4 out of the right side and if you do sumthing to one side you gotta do it to the other

200 divided by 4= 0.50(Vf+10)
50= 0.50(Vf+10)

Now expand the 0.50

So 50= 0.5Vf + 5 (because 0.5 times 10 is 5)

Now get rid of the 5

50-5= 0.5Vf

45 =0.5Vf now Divide the 0.5 out

45 divided by 0.5 = Vf

And 45/0.5 is 90

So 90=Vf

Therefore the final Velocity is 90m/s
