Someone is not paying attention while speeding down the tramway. Their truck has a mass of 2000 kg. Going a whopping 34.1 m/s (7

6.3 mph) the truck crashes into a stationary Corolla (mass of 1100 kg). If the truck comes to a complete stop, how fast does the Corolla slide forward when it is hit

Answer:

Explanation:

This question comes from Conservation of Momentum

M1=2000kg

U1=34.1ms^-1

Now this truck crashes into a stationary corolla

Since its stationary

U2=0

M2=1100kg

The Moving Truck came to a complete stop(or rest)

Its Final Velocity V1=0

Mass still remains the same

The corolla will move with a speed V2

Applying the formula for conversation of Momentum

M1U1 + M2U2 = M1V1 + M2V2

2000(34.1) + 1100(0) = 2000(0) + 1100(V2)

2000(34.1) = 1100(V2)

V2 = 2000(34.1)/1100

V2 =62ms^-1

Which form of Kepler’s third law can you use to relate the period T and radius r of a planet in our solar system as long as the
ser-zykov [4K]

T2=r In the form of Kepler's law that can use to relate the period T and radius of the planet in our solar systems

<u>Explanation:</u>

<u>Kepler's third law:</u>

  • Kepler's third law states that For all planets, the square of the orbital

     period (T) of a planet is proportional to the cube of the average orbital    radius (R).

  • In simple words T (square) is proportional to the R(cube) T²2 ∝1 R³3
  • T2 / R3 = constant = 4π ² /GM

      where G = 6.67 x 10-11 N-m2 /kg2

        M = mass of the foci body
