The F Ring, the Cassini Division, and the C Ring are bright ring features. They are bright due to the low concentration of materials within them, which allows sunlight to shine through.
This problem applies momentum balance over the cars collided
m1v1y + m2v2y = (m1 + m2)v'y
<span>0 + (1500 kg)(25.0 m/s) = (2500 kg)v'y </span>
<span>v'y = 15.0 m/s </span>
<span>Find the vector sum of the velocities: </span>
<span>v^2 = v'x^2 + v'y^2 = (8.00 m/s)^2 + (15.0 m/s)^2 </span>
<span>v = 17.0 m/s </span>
<span>find the angle: θ = tan^-1(15.0 m/s / 8.00 m/s) = 61.9° </span>
<span>now, the momentum: p = mv = (2500 kg)(17.0 m/s) </span>
<span>p = 4.25 x 10^4 kg x m/s at 61.9° N of E</span>
Answer: a= 4.4ms-2
Displacement= 26.95 m
Explanation:
First, the speed in km/hr must be converted to m/s so that we can apply it in solving the question. The motion started from rest hence the initial velocity is 0m/s. The average displacement is also obtained from the equations of motion as shown in the image attached.
Answer:
Density = Mass / Volume
Mass = .3 kg
Volume = 2 * 5 * 4 = 40 m^3
Density = .3 g / 40 m^3 = .0075 kg / m^3
1 kg/m^3 = kg * 1000 g / kg / (1 m^3 * (100 cm/m)^3) = 10E-3 gm/cm^3
Density = 7.5 E-3 gm/cm^3
