I believe the answer is B.
Using the impulse-momentum theorem and taking this down as positive, we will get:
FΔt = Δp
F = Δp / Δt
= m(v - v₀) / t
= 0.056kg [13m/s - (- 20m/s) / 0.00125s
= 1478.4 N when properly rounded off is the answer we are looking for in this problem.
Answer:
Plasma is by far the most common form of matter. Plasma in the stars and in the tenuous space between them makes up over 99% of the visible universe and perhaps most of that which is not visible. On earth we live upon an island of "ordinary" matter.
The period T of a pendulum of length L is given by
where g is the free-fall acceleration value.
Given that on Xenos T=1.57 s and L=1.59 m, we can re-arrange the formula and replacing these numbers to find the value of g on Xenos:
