Answer:
Say you are holding a thread to the end of which is tied a stone. Now when you start whirling it around you will notice that two forces have to be applied simultaneously. One which pulls the thread inwards and the other which throws it sideways or tangentially.
Both these forces will generate their respective accelerations.
The one pointed inwards will generate centripetal or radial acceleration.
The one pointing sideways will generate tangential acceleratio
Explanation:
A major difference between tangential acceleration and centripetal acceleration is their direction
Centripetal means “center seeking”. Centripetal acceleration is always directed inward.
Tangential acceleration is always directed tangent to the circle.
Tangential acceleration results from the change in magnitude of the tangential velocity of an
object. An object can move in a circle and not have any tangential acceleration. No tangential
acceleration simply means the angular acceleration of the object is zero and the object is moving
with a constant angular velocity
Answer:
Explanation:
According to energy conservation which states that the workdone is equal to change in the system
Workdone = change in kinetic energy + (frictional force * distance)
Workdone = ΔK + fd
Workdone = kf-Ki + fd
Workdone = = 1/2(m(v-u)^2) + fd
Given
Mass m = 495kg
final velocity v = 105m/s
initial velocity = 0m/s
Force f= 1400N
distance d = 395m
Substitute
Workdone = 1/2(495(105-0)^2) + 1400(395)
Workdone = 2,728,687.5+553000
Workdone = 3,281,687.5 Joules
Time = 8.2secs
Power output = Workdone/Time
Power output = 3,281,687.5/8.2
Power output = 885,766.768
Power output = 8.858 * 10^5 watts
When two atoms of the same nonmetal react,they form what we know today as a diatomic molecule.

Answer:
Explanation:
Recall the formula for linear momentum (p):
which in our case equals 26.4 kg m/s
and notice that the kinetic energy can be written in terms of the linear momentum (p) as shown below:
Then, we can solve for the mass (m) given the information we have on the kinetic energy and momentum of the particle:
Now by knowing the particle's mass, we use the momentum formula to find its speed:
