A rocket is moving with constant velocity of 2000ms and accelerates uniformly at 10ms. What is the velocity after 5 minutes?

A 1.00 -kg object slides to the right on a surface having a coefficient of kinetic friction 0.250 (Fig. P8.62a). The object has

LekaFEV [45]

The distance D where the object comes to rest is 1.08.m.

<h3>What is the distance?</h3>

The separation of one thing from another in space; the distance or separation in space between two objects, points, lines, etc.; remoteness. The distance of seven miles cannot be accomplished in one hour of walking.
Learn how to use the Pythagorean theorem to get the separation between two points using the distance formula. The Pythagorean theorem can be rewritten as d==(((x 2-x 1)2+(y 2-y 1)2)
The distance between any two places is the length of the line segment separating them. By measuring the length of the line segment that connects the two points in coordinate geometry, the distance between them may be calculated.

(c) the distance D where the object comes to rest.

$W_{total} =$ ΔKE ⇒ -0.25*1*9.8*D = 0-1/2*1* $2.3^{2}$

⇒ $D=\frac{0.5*2.3^{2} }{2.45}$

⇒1.08.m

What should a sailboat operator do when approaching a PWC head-on

nekit [7.7K]

In accordance with the International Regulation for the prevention of collisions at sea:

1.- A sailing boat has a passing preference over a motorized boat, except when the motor boat is limited by its draft.

2.- The sailboat must maintain its course and speed.

3.- If it is evident that the PWC does not respond, the sailboat must sound the warning signal, and change its course to starboard.

4.- All actions must be taken as soon as possible.

5.- If a sailboat is using its engine, the situation changes, and in that case, both ships must alter to starboard.

N object has a charge of -2.0 μc. how many electrons must be removed so that the charge becomes +2.2 μc?

balandron [24]

Electrical Charge is a property of matter that causes it to experience a force when place in an electromagnetic field. Charge is measured in coulombs.
The change in the charge is 2.2- (2.0)= 4.2 μ c.
1 electron has a charge of 1.6 ×10∧-19 coulombs
Therefore, the number of electrons will be;
= (4.2 ×10∧-6)/ (1.6 ×10∧-19)
= 2.625 × 10∧13 electrons

Suppose that a constant force is applied to an object. newton's second law of motion states that the acceleration of the object

amm1812

Solve for "x"
X = speed of the 5 kg
3/15=5/x
cross multiply
3x=75
because (15)(5)=(3)(x)
divide 3 in both side
X=25
or
A=25 m/s^2
Hope this helps

the period of a mechanical wave is 12 seconds what is the frequency of the wave 12 waves/seconds 4.0 waves/seconds 0.083 waves/s

Mandarinka [93]

Use your units !
"Period" is time . . . 12 seconds.
"Frequency" how often . . . " ___ PER time". Time is in the denominator.

"12 seconds per wave" means

      1 wave / 12 seconds

   = ( 1 / 12 ) (wave/second)

   = 0.08333... wave per second

   =    1/12 Hz.
