Answer:
C!!
Explanation:
Combining all manufacturing processes to provide higher efficiency and fulfilling the requeriments.
Answer:T = 167.3 N
Explanation:
Given that the
Weight mg = 110 N
The mass m of the ball will be
m = 110/9.8 = 11.22 kg
As the direction of the ball’s velocity is changing, the force responsible for this is centripetal force F. And
F = mV^2/r
Where
V = 5.0 m/s
r = L = 4.9 m
m = 11.22
Substitute all these parameters into the formula
F = (11.22 × 5^2)/4.9
F = 280.6/4.9
F = 57.27 N
Tension T = F + mg
Substitute F and mg into the formula
T = 57.27 + 110
T = 167.3 N
Therefore, the tension in the rope at that point is 167.3 N
