Q3. Impulse is a
Answer : Option D
Explaination / Solution:
Since force is a vector quantity, impulse is also a vector in the same direction.
Impulse J produced from time t1 to t2 is defined to be
where F is the resultant force applied from t1 to t2
force is related to momentum p by
F = dp/dt
therefore,
where is the change in linear momentum from time t1 to t2
