Square root of (4^2 + 4^2) = 4*squareRoot(2)
Answer:
5.3 kg
Explanation:
The rope attached to the ceiling has a tension 64 N.
The rope attached to the wall has a tension T.
The rope attached to the block has a tension Mg.
Sum of the forces at the junction in the y direction:
64 sin 55° − Mg = 0
Mg = 64 sin 55°
M = 64 sin 55° / g
M = 64 sin 55° / 9.8
M = 5.3
The mass of the block is 5.3 kg.

Answer:
<h2>10 kg.m/s</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 20 × 0.5
We have the final answer as
<h3>10 kg.m/s</h3>
Hope this helps you
Answer:
11.48 degree N of W
Explanation:
We are given that
Wind velocity=km/h
Because wind is blowing towards south
Air speed=
Because the captain want to move with air speed in west direction.
x component of relative velocity=-212 km/h
y-Component of relative velocity=-43km/h
Direction=
N of W
Hence, the direction in which the pilot should set her course to travel due west=11.48 degree N of W
