Ummm It is given that,
Mass of bumper car, m₁ = 202 kg
Initial speed of the bumper car, u₁ = 8.5 m/s
Mass of the other car, m₂ = 355 kg
Initial velocity of the other car is 0 as it at rest, u₂ = 0
Final velocity of the other car after collision, v₂ = 5.8 m/s
Let p₁ is momentum of of 202 kg car, p₁ = m₁v₁
Using the conservation of linear momentum as :
p₁ = m₁v₁ = -342 kg-m/s
So, the momentum of the 202 kg car afterwards is 342 kg-m/s. Hence, this is the required solution.
Answer:
Proof is given below
Explanation:
The length contraction is given by Δx = Δx' *√(1 - v² / c²)
where Δx' is the proper length and is measured in the frame where the object is at rest
Since the y' and z' axes are perpendicular to the direction of motion there is no contraction
So if you let V0 = Δy' * Δz' *Δx'
and V = Δy * Δz * Δx = Δy'* Δz' * Δx
Then
V = V0 * √(1 - v² / c²)
Given data:
* The acceleration of the runner is,
* The initial velocity of the runner is,
* The time given is,
Solution:
By the kinematics equation, the final velocity of the runner is,
where v is the final velocity,
Substituting the known values,
Thus, the final velocity of the runner is 30.67 m/s.
Answer:
A spiral galaxy in which Earth is located
Explanation:
Because spiral galaxies are characterized by a distinct flattened spiral disk with a bright center called the nucleus making it lookl ike a hurricane symbol on weather hurricane trackers. Our very own Milky Way is a spiral galaxy and Eaerth is located rigth in their.
