Question

A ball falls from height h. After 1 second, another ball talls 21. Two vectors A and B inclined at an angle have a resultant R freely from a point 20 m below the point from where the first ball falls. Both of them reach the ground at the same time. What is the value of h? (Take g = 10 ms)
(a) 11.2 m (b) 21.2 m (c) 31.2 m (d) 41.2 m

Answer 1

Explanation:

Two vectors A and B inclined at an angle h… ... A and B inclined at an angle have a resultant R freely from a point 20 m below the point from where the first ball falls.
