Answer:
14.04 m/s
Explanation:
To find the velocity of the first car after the collision, we can use the equation of conservation of momentum:
m1v1 + m2v2 = m1'v1' + m2'v2'
We have the following data:
m1 = m1' = 328,
m2 = m2' = 790,
v1 = 19.1,
v2 = 13,
v2' = 15.1.
Using this data, we can find v1' (final velocity of the first car):
328 * 19.1 + 790 * 13 = 328 * v1' + 790 * 15.1
16534.8 = 328 * v1' + 11929
328 * v1' = 4605.8
v1' = 14.04 m/s

Explanation:
the side with most net force is going to be deducted by the side with the least net force.
Answer:
4.44586579653 rpm
Explanation:
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
M = Mass of Europa =
R = Radius of Europa =
r = Radius of arm = 6 m
= Angular velocity
Acceleration due to gravity is given by
Now, equating the above value with the motion of the arm
Converting to rpm
The angular speed of the arm is 4.44586579653 rpm
