35. What would a ship's position be if that ship started at

Tcecarenko [31]

Answer:

The final position of the ship after the given time period is 42 km West of B.

Explanation:

Given;

average velocity of the ship, v = 35 km/h

time taken for the ship to reach point D, t = 1.2 hours

The position of the ship after the given time period is calculated as follows;

x = v x t

x = (35 km/h) x 1.2 h = 42 km

x = 42 km West of B.

Therefore, the final position of the ship after the given time period is 42 km West of B.

A car is going along a circular road at a constant speed. The radius of the curve is 242 m, and the car takes 1.3 minutes to com

Dvinal [7]

Answer:

$a_c=1.57\frac{m}{s^2}$

Explanation:

In order to find its centripetal acceleration we need to use the next equation:

$a_c=\frac{v^2}{r}$

So, we need to find its velocity in first place. Considering that the time T required for one complete revolution is called the period. For constant speed is given by:

$T=\frac{2\pi r}{v}$

Solving for v, considering that in this case T=1.3min=78s, and r=242

$v=\frac{2\pi *(242)}{78} =19.49398518m/s$

Finally, replacing v in the centripetal acceleration equation:

$a_c=\frac{(19.49398518)^{2} }{242}=1.570311811m/s^2$

If the velocity of a body changes from 13 m/s to 30 m/s while undergoing constant acceleration, what's the average velocity of t

vesna_86 [32]

Average velocity is found by the following formula:

$v_{average} = \frac{v_f+v_i}{2}$

$v_i = 13 \\ v_f = 30 \\ v_{average} = \frac{30+13}{2} = \frac{43}{2} = 21.5 \frac{m}{s}$

19*9.8*32.4 = 6,032.9 rounded

honestly, I do not know if this is correct so please don't come back at me

hopefully this helps

Explanation: [do the following, if you think I am wrong]

just pick a formula,

plug in the number to the mass, gravity, and height

than multiply

get your answer, but don't forget to round to the nearest tenth
