Answer:
-7.072 °
Step-by-step explanation:
According to the given data, angular position is defined by
angular position = 17 ° cos( wt)
Where,
w is the angular frequency
w = √(g/L)
where,
L= length and g = acceleration due to gravity =>9.8m/s²
angle = 17 ° cos( √(g/L) t) ---->(note to solve your calculate should be in radian mode)
At t=0.35s
angle = 17 ° x -0.416
angle= -7.072 °
Therefore, the angular position of the pendulum at t = 0.35s is -7.072 °
