Given below the arrangement of loading on the larger boat by two tug boats.
F₁ = 5 N
F₂ = 4 N
Angle between them θ = 90⁰
Resultant between two vectors,
Substituting
So magnitude of the net force on the block = 6.403 N
An astronaut lands on an alien planet. He places a pendulum (L = 0.200 m) on the surface and sets it in simple harmonic motion,
as shown in this graph.
(a) What is the period and frequency of the pendulum’s motion?
(b) How many seconds out of phase with the displacements shown would graphs of the velocity and acceleration be?
(c) What is the acceleration due to gravity on the surface of the planet in? Determine the number of g-forces.
Show any necessary calculations.
