The term "meter" is the name chosen for the SI standard unit of length and distance.<em> (C)</em>

The SI standard unit of mass is called the "kilogram".

The unit of area is the square-meter or meter².

The unit of volume is the cubic meter or meter³.

A large crate sits on the floor of a warehouse. Paul and Bob apply constant horizontal forces to the crate. The force applied by
Delicious77 [7]

Answer:

W = -510.98J

Explanation:

Force = 43N, 61° SW

Displacement = 12m, 22° NE

Work done is given as:

W = F*d*cosA

where A = angle between force and displacement.

Angle between force and displacement, A = 61 + 90 + 22 = 172°

W = 43 * 12 * cos172

W = -510.98J

The negative sign shows that the work done is in the opposite direction of the force applied to it.

Neglect air resistance in this question. If you drop a ball from a height of 4.9 m, it will hit the ground 1s later. If you fire
olchik [2.2K]

Answer:

Explanation:

The time at which an object from from rest depends on air resistance, the height, gravity.

Since the question says we should neglect air resistance and both the ball and the bullet are from the same height they will get to the ground and the same time since they are both fired on earth which has the same gravity..

H=ut+1/2gt^2.

For an object dropping from a height the initial velocity is zero, therefore u=0m/s.

The formula becomes

t=√(2H/g)

So the time and object get to the ground depends on the height from the ground and gravity...

So since no air resistance they will get to the ground together.

A 500,000 kg cargo ship is traveling at 75 km/h when its engine is shut off. The magnitude of the frictional force between boat
Ymorist [56]

Answer:1.8 hr

Explanation:

Given

mass of cargo=500,000 kg

initial speed=75 km/h\approx 20.833 m/s

Frictional force=85 v

at t=0 engine is shut off so acquired speed is slowly decreasing

85v=-500,000\frac{\mathrm{d} v}{\mathrm{d} t}

85dt=-\frac{dv}{v}

Integrating both sides

85\int_{0}^{t}dt=-500,000\int_{20.83}^{6.944}\frac{dv}{v}

85t=500,000\ln \frac{1}{3}

t=6462.425 s

t=1.8 hr
