A body of mass 5kg movimg with a velocity of 30... - WAEC Physics 2009 Question
A body of mass 5kg movimg with a velocity of 30ms-1 due east is suddenly hit by another body and changes its velocity to 50ms-1 in the same direction. Calculate the magnitude of the impulse received.
A
100Ns
B
150Ns
C
250Ns
D
400Ns
correct option: a
I = Ft = m(v - u)
= 5(50 - 30) = 100
= 5(50 - 30) = 100
