@ representing coefficient of kinetic friction.
thus 19.5/51.7 = 0.377
Answer:
Momentum of alpha particle is 1.4752x10^-19 kg-m/s
Explanation:
Detailed explanation and calculation is shown in the image below
The speed of spaceship moving is 2.4 x 10^8 m/s
As from the given data, the clock in a spaceship is observed to run at a speed of 3/5 of a similar clock that rest on the earth is
T/T° = 3/5
The expression for the time dilation is given by
T = γT°
γ = T/T°
γ = 1/√1 - v^2/c^2 is time dilation
Substituting the values in the above equation as,
γ = T/T°
5/3 = 1/√1 - v^2/c^2
v^2/c^2 = 16/25
v = 0.8 c
v = 0.8 x 3 x 10^8 m/s
v = 2.4 x 10^8 m/s
Hence, speed of spaceship moving is 2.4 x 10^8 m/s
