Answer:
2.23 m/s²
Explanation:
mass of sail boat, m = 20600 kg
Force along east, F1 = 17700 N
Force along north west, F2 = 60000 N
write the forces in vector form
Net force acting on the boat
The magnitude of net force is given by
F = 45922 N
Acceleration = force / mass
a = 45922 / 20600
a = 2.23 m/s²
Answer:
retains a fixed volume and shape
rigid - particles locked into place
not easily compressible
little free space between particles
does not flow easily
rigid - particles cannot move/slide past one another

Answer:
Explanation:
given,
size of door = 1 m x 2 m
total mass = 44 Kg
mud mass attached = 0.700 Kg
speed of door = 14 m/s
angular speed of door = ?
conservation of angular momentum
initial angular momentum is equal to final momentum
To solve this question, we need to use the component method and split our displacements into their x and y vectors. We will assign north and east as the positive directions.
The first movement of 25m west is already split. x = -25m, y = 0m.
The second movement of 45m [E60N] needs to be split using trig.
x = 45cos60 = 22.5m
y = 45sin60 = 39.0m
Then, we add the two x and two y displacements to get the total displacement in each direction.
x = -25m + 22.5m = -2.5m
y = 0m + 39.0m
We can use Pythagorean theorem to find the total displacement.
d² = x² + y²
d = √(-2.5² + 39²)
d = 39.08m
And then we can use tan to find the angle.
inversetan(y/x) = angle
inversetan(39/2.5) = 86.3
Therefore, the total displacement is 39.08m [W86.3N]
DISTANCE
-length of the path between two points
-doesn't have to be a straight path
-has no direction
DISPLACEMENT
-the length from the starting point to the ending point
-must be a straight path
-must have direction (north, south, east, west, up, down)
EXAMPLE-If you wanted to know the distance from your house to the park, you could say 'three blocks north and then two blocks west' but for displacement, you could just cut through houses and backyards to get to the destination.
Hope that makes some sense :)
