A 0.22 kg air track glider moving at 0.60 m/s a collides elastically into a 0.44 kg glider at rest. After collision the 0.22 kg

The glider collides elastically  an another glider at rest, in this case we have the coservation of quantity of movement 

m1 v1  + m2 v2 = m1V1 + m2 V2
v is the velocity before the shock, V the velocity after the shock
m1=0.22
v1=0.60m/s
m2=0.44
V1=-0.20m/s
remark that <span>0.44 kg glider is initially at rest, so v2= 0
the equation above can be written  </span><span>m1 v1  = m1V1 + m2 V2 ( because v2=0 at rest)
</span><span>m1 v1  = m1V1 + m2 V2 implies  V2= (m1v1 -m1V1) / m2
</span>
V2=0.22x0.60 -0.22x (-0.20) ] / 0.44= 0.4m/s

Didifference between uniform and variable velocity <br>​
Simora [160]

Answer:

Uniform velocity is scalar , while variable velocity is vector

Explanation: Uniform velocity and variable velocity is that a body moving with uniform velocity has zero acceleration, while a body that is moving with variable velocity has some acceleration. Uniform velocity is the vector quantity while non-uniform or variable velocity is a scalar quantity

A 562 N trunk is on frictionless plane inclined at 30.0 degrees from the horizontal. What is the acceleration of the trunk down
Len [333]

Answer: 0m/s²

Explanation:

Since the forces acting along the plane are frictional force(Ff) and moving force(Fm), we will take the sum of the forces along the plane

According newton's law of motion

Summation of forces along the plane = mass × acceleration

Frictional force is always acting upwards the plane since the body will always tends to slide downwards on an inclined plane and the moving acts down the plane

Ff = nR where

n is coefficient of friction = tan(theta)

R is normal reaction = Wcos(theta)

Fm = Wsin(theta)

Substituting in the formula of newton's first law we have;

Fm-Ff = ma

Wsin(theta) - nR = ma

Wsin(theta) - n(Wcos(theta)) = ma... 1

Given

W = 562N, theta = 30°, n = tan30°, m = 56.2kg

Substituting in eqn 1,

562sin30° - tan30°(562cos30°) = 56.2a

281 - 281 = 56.2a

0 = 56.2a

a = 0m/s²

This shows that the trunk is not accelerating
