Answer:
11.3 g
Explanation:
given,
density of the lead = 11.3 g/cm³
volume = 1 cm³
mass of the lead = ?
we know,
mass = volume x density
mass = 1 x 11.3
mass = 11.3 g
hence, the mass of the lead is equal to 11.3 g
Answer:
Vw = 0.98m/s due 67.16° north of east
Explanation:
The distance the canoeist wants to travel is:
And the angle of the destination point is
With this trajectory and the time of 42s, we get the velocity of the canoe respect to ground:
Now we can calculate the velocity of the water:
Answer:force equals to rate of change of momentum
Explanation:
F=force
t=time
m=mass
v=final velocity
u=initial velocity
(mv-mu)/t=rate of change of momentum
Force=rate of change of momentum
F=(mv-mu)/t
