Answer:
a = 0.01 [m/s²]
Explanation:
To solve this problem we must use Newton's second law, which says that the sum of forces on a body is equal to the product of mass by acceleration.
ΣF = m*a
where:
F = forces = 10 [N]
m = mass = 100 [kg]
a = acceleration [m/s²]
10 = 100*a
a = 0.01 [m/s²]
Answer:
angle of incidence for the second mirror is 55.4 degree
Explanation:
Given data;
Angle between two mirror is 90 degree
Incident angle on first mirror is 34.6 degree
For first mirror
Angle of incidence is equal to angle of reflection
34.6 degree = angle of reflection

Now , for the triangle ABC [from figure]



The angle of incidence for
angle of incidence for the second mirror is 55.4 degree
Explanation:
Fnet = Ft - Ff = 60N - 20N = 40N
a = Fnet / m = 40N / 25kg = 1.6m/s².
Answer:
120 m
Explanation:
We can calculate the period of a pendulum using the following expression.

where,
T is the period of the pendulum
L is the length of the pendulum (here it coincides with the height of the tower)
g is the gravity
