Physics

7 0

Answer:

a = 0.711 m/s^2

Explanation:

As we know that truck is moving up the hill

So here we have two forces on the crate placed on the truck

1) gravitational force along the floor

2) Friction force along the floor

Now here if the truck is moving with maximum possible acceleration so that there is no slipping of the crate

So here we will have

\mu mg cos\theta - mgsin\theta = ma

a = \mu g cos\theta - g sin\theta

a = (0.25)(9.81)cos10 - 9.81 sin10

a = 0.711 m/s^2

How long does a 50 kW pump motor have to run to pump 500 cubic meters of water from a 180m deep mine
Ghella [55]

Answer:

t = 17658 s = 294.3 min = 4.9 h

Explanation:

The general formula for power is:

P = \frac{W}{t}

where,

P = Power of the Motor = 50 KW = 50000 W

W = Work Done by Motor = Change in P.E of Water = mgh

g = acceleration due to gravity = 9.81 m/s²

m = mass of  water = ρV

h = depth of water = 180 m

ρ = density of water = 1000 kg/m³

V = Volume of Water = 500 m³

t = time taken = ?

Therefore,

P = \frac{mgh}{t}=\frac{\rho Vgh}{t}\\\\t = \frac{\rho Vgh}{P}\\\\t = \frac{(1000\ kg/m^3)(500\ m^3)(9.81\ m/s^2)(180\ m)}{50000\ W}\\\\

<u>t = 17658 s = 294.3 min = 4.9 h</u>

What is the velocity of a jet plane that travels 48 meters East in 4 seconds?
soldier1979 [14.2K]

Answer:

the speed of a jet plane = v = 12 m/s

Explanation:

jet plane that travels 48 meters East in 4 seconds?

<u>use the velocity as distance over time formula = v = d / t</u>

where:

t = 4 sec

d = 48 m

plugin values into the formula

v = <u>  48 m  </u>

        4 sec

v = 12 m/s

therefore,

the speed of a jet plane = v = 12 m/s

Explain what will happen if an object has high momentum or low momentum and a force is applied?
Korvikt [17]

-- If the force is applied in the <em>same direction</em> as the object is moving, then the object's momentum in that direction will <em>increase</em>.

-- If the force is applied in the direction <em>OPPOSITE </em>to the way the object is moving, then the object's momentum will <em>decrease</em>.

-- In either case, the CHANGE in the object's momentum will be

(strength of the force) x (length of time the force is applied) .

This quantity is also called "impulse".
