Acceleration due to gravity on the surface of radius R = GM/R^2 = 9.8 m/s^2
weight at surface of earth = mg = 78 x 9.8 = 764.4 N
acceleration due to gravity at 6R = GM/(6R)^2
= GM/R^2 /36
=9.8/36 = 0.27 m/s^2
weight on spacecraft = 78 x 0.27 = 21.2 N
Answer:
Total momentum = 16 Kgm/s
Explanation:
Let the momentum of the two balls be A and B respectively.
Momentum A = 16 kgm/s
Momentum B = 0 kgm/s (since the ball is at rest).
Total momentum = A + B
Total momentum = 16 + 0
Total momentum = 16 Kgm/s
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
The wavelength would decrease because frequency is inversly proportional to the wavelength provided the speed is constant: f=v/λ
