Answer:
F=124.03 N
Explanation:
Given data
mass m=5.00 kg
y(t)=(2.80 m/s)t+(0.61m/s³)t³
To find
Force F at t=4.10 s
Solution
As
derivative with respect to time we get
again derivative with respect to time to get acceleration
at t=4.10 s then a(t) is
a=3.66(4.10)
a=15.006 m/s²
Now to use Newton law to find force in y direction
Answer:
do we have to choose 2 answers here?
Answer:
Send a pic of it so i can mark it.
Explanation:
Answer:
a. 86.80 m
b. i. The mass of the bob
ii. The length of the pendulum
Explanation:
a. Determine the height of the smokestack.
Using T = 2π√(L/g) where T = period of pendulum = 18.7 s, L = length of pendulum = height of smokestack and g = acceleration due to gravity = 9.8 m/s².
So, making L subject of the formula, we have
T = 2π√(L/g)
T/2π = √(L/g)
squaring both sides, we have
(T/2π)² = L/g
L = (T/2π)²g
Substituting the values of the variables into the equation, we have
L = (T/2π)²g
L = (18.7 s/2π)²(9.8 m/s²)
L = (2.976 s)²(9.8 m/s²)
L = 8.857 s² × 9.8 m/s²
L = 86.796 m
L ≅ 86.80 m
b. What factors influence the period of a simple pendulum
The factors that influence the period of a simple pendulum are
i. The mass of the bob
ii. The length of the pendulum
