Question

An object od mass 50 kg accelerates from a velocity of 2 m/s to a velocity of 10 m/s in the same direction
What is the impulse provided to cause this acceleration?
A. 250 N s
B. 400 N s
C. 850 N s
D. 2500 N s
(and explain)

Answer 1

f. t(impulse)=change in momentum
so impulse =50*(10-2)=400Ns
so your answer is B i.e. 400Ns

Answer 2

Given :

Mass of object , m = 50 kg .

Initial velocity , u = 2 m/s .

Final velocity , v = 10 m/s .

To Find :

The impulse provided to cause this acceleration .

Solution :

We know , Impulse in given by :

$I=m(u-v)\\\\I=50\times (10-2)\ kg \ m/s\\\\I=400\ kg\ m/s$

Therefore ,  the impulse provided to cause this acceleration is 400 kg m/s .

Hence , this is the required solution .
