During maneuvers preceding the Battle of Jutland, the British battle cruiser Lion moved as follows (in nautical miles): 1.2 mile

lana66690 [7]

Answer:

total distance is 11.3 miles

Explanation:

Given data:

distance to north = 1.2 miles

distance to south at 38 degree east of south = 6.1 miles

distance to east of north at angle 89 degree = 4 miles

distance to east of north at angle 31 degree = 6.5 miles

considering each displacement as vector so we have

$\begin{pmatrix}0.0\\ 1.2\end {pmatrix} + \begin {pmatrix}3.8\\ -4.8\end{pmatrix} +\begin{pmatrix}4.0\\ 0.1\end {pmatrix}+\begin{pmatrix}3.3\\ 5.6\end{pmatrix} = \begin{pmatrix}11.1\\ 2.1\end{pmatrix}$

total distance is $\sqrt{11.1^2 + 2.1^2} \approx 11.3$

the roque requried to turn the crank on an ice cream maker is 4.50 N.m how much work does it take to turn the crank through 300

Alexus [3.1K]

Answer:

the work required to turn the crank at the given revolutions is 8,483.4 J

Explanation:

Given;

torque required to turn the crank, T = 4.50 N.m

number of revolutions, = 300 turns

The work required to turn the crank is given as;

W = 2πT

W = 2 x 3.142 x 4.5

W = 28.278 J

1 revolution = 28.278 J

300 revlotions = ?

= 300 x 28.278 J

= 8,483.4 J

Therefore, the work required to turn the crank at the given revolutions is 8,483.4 J
