Bambi is walking along the train tracks when he suddenly notices a fast approaching train and freezes in his tracks like a deer

in headlights. IF the 1000kg train collides with Bambi at a speed of 8 m/s, and Bambi, who weighs 75kg, gets stuck to the front of the train, how fast will the train and Bambi continue to move after the collision

Answer:

The final speed of the train and Bambi after collision is 7.44 m/s

Explanation:

Given;

mass of the train, m₁ = 1000kg

mass of  Bambi, m₂ = 75kg

initial speed of the train, u₁ =  8 m/s

initial speed of Bambi, u₂ =  0 m/s

If Bambi gets stuck to the front of the train, then the collision is inelastic.

m₁u₁ + m₂u₂ = v(m₁ + m₂)

where;

v is the final speed of the train and Bambi after collision

Substitute the given values and solve for v

1000 x 8 + 75 x 0 = v (1000 + 75)

8000 = v (1075)

v = 8000/1075

v = 7.44 m/s

Therefore, the final speed of the train and Bambi after collision is 7.44 m/s

Which change occurs when an atom undergoes alpha decay?
oee [108]
In an alpha decay, an atom emits an alpha particle. An alpha particle consists of 2 protons and 2 neutrons: this means that during this kind of decay, the original atom loses 2 protons and 2 neutrons from its nucleus.

This also means that the atomic number Z of the element (the atomic number is the number of protons in the nucleus) decreases by 2 units in the process, while the mass number A (the mass number is the sum of the number of protons and neutrons) decreases by 4 units.

The distance from earth to mars ranges between 780,000,000 km and 380,000,000 km depending on the time of the year. The speed of
ivann1987 [24]

Answer:

The minimum time, t = 21.11 m

Explanation:

Given,

The maximum distance between the Earth and Mars, d = 780,000,000 km

The maximum distance between the Earth and Mars, d = 780,000,000 km

The speed of the light, c = 300,000 km/s

The distance and speed of the object is related using the formula,

                           v = d / t

                            t = d / v

The minimum time it takes for data transmission is when the distance between the Mars and the Earth is at minimum.

Therefore,

                            t = 380,000,000 km / 300,000 km/s

                              = 1266.67 s

                              = 21.11 minutes

Hence, the minimum time it takes for data transmitted by the Mars Surveyor to reach earth, t = 21.11 minutes
