Mass and velocity are the two terms which affect momentum of a bicycle going hill down.

Explanation:

As we know that Momentum describes the motion of an object. It is the combination of the objects mass and velocity.

So, obviously with no doubt mass and velocity are the two terms which affect momentum.

Momentum(p) = Mass(m) * Velocity(v)

The momentum also depends upon the mass and speed of the object.

More the mass of the object more is the momentum.

Depending upon the gravity and bicycle's motion speed momentum varies.

Bicycle moves faster the down hill if it moves with some speed as it has lesser mass the momentum also will be less.

Three forces with magnitudes of 95 pounds, 75 pounds, and 146 pounds act on an object at angles 100°, 200°, and 300°, respective

VladimirAG [237]

Answer:

Explanation:

We shall represent all the forces in vector form .

Force of 95 pounds

F₁ = 95cos100 i + 95sin100j

= -16.5 i +93.55 j

force of 75 pounds

F₂ = 75cos200 + 75sin200j

= -70.47 i - 25.65 j

force of 146 pounds

F₃ = 146cos300 i + 146sin300j

= 73i -126.44 j

Resultant force

R = F₁+ F₂ + F₃

= -16.5 i +93.55 j -70.47 i - 25.65 j +73i -126.44 j

= -13.97 i - 58.54 j

Magnitude of R = √ ( 13.97² + 58.54² )

= 60.18

If Ф be angle of resultant with axis

tanФ = - 58.54 / -13.97

Ф = 76.57 + 180 = 256.57 , because both x and y components are negative. So the resultant will be in third quadrant.

A 1470-kilogram truck moving with a speed of 27.0 m/s runs into the rear end of a 1010-kilogram stationary car. If the collision

Gre4nikov [31]

Answer:

$\Delta KE = 218.375\ kJ$

Explanation:

Given,

Mass of the truck, M = 1470 Kg

initial speed of the truck, u = 27 m/s

mass of car, m = 1010 Kg

initial speed of car, u' = 0 m/s

Final speed, V = ?

Using conservation of momentum

$Mu = (M+m) V$

$1470\times 27 = (1470 + 1010 ) V$

$V = 16\ m/s$

Change in kinetic energy

$\Delta KE = \dfrac{1}{2} Mu^2 - \dfrac{1}{2}(M+m)V^2$

$\Delta KE = \dfrac{1}{2}\times 1470\times 27^2 - \dfrac{1}{2}\times (1470 + 1010)\times 16^2$

$\Delta KE = 218.375\ kJ$

Change in KE = $\Delta KE = 218.375\ kJ$

How do I calculate the speed of light and the distance between the earth and the moon?

MAVERICK [17]

To calculate the distance to a star, astronomers observe it from different places along Earth's orbit around the Sun. If they measure the object's position several months apart, their "two eyes" will have a separation of well over 100 million miles!
