Question

14. What is the velocity of the bob of a simple pendulum at its mean position, if it is able to rise to vertical height of 10 cm
(Take g =9.8m/s?
(a) 0.6 m/s
(b) 1.4 m/s
(c) 1.8 m/s
(d) 2.2 m/s​

Answer 1

Answer:

1.4m/s is the aswer hope it helps

Answer 2

Answer:

b)1.4

Explanation:

total displacement of the Bob is 10 cm or 0.1 m

initial velocity(u) is zero

acceleration due to gravity is 9.8

so by using formula:v²=u²+2as

we get

v²=0²+2×9.8×0.1

after calculating

v=1.4
