A one-dimensional force F varies with time according to the given graph. Calculate impulse of the force in following time intervals.
(a) From `t=0s` to `t=10s`.
From `t=10 s` to `t=15s`.
(C) From `t=0 s` to `t=15s`.

Text Solution

Verified by Experts

For one-dimensional force, impulse equals to area between force-time graph and the time axis. (a) `I_(0rarr10)=` Area of trapazium `OABC=75N-s`
(b) `I_(10rarr15)= -` Area of triangle `CDE=-25N-s`
(c ) `I_(0 rarr 15) =` Area of trapazium `OABC-` Area of triangle `CDE=50 N-s`
