A time-varying horizontal force F(t) = At4 + Bt2 acts for 0.500 s on a 12.25-kg object, starting at time t = 1.00 s. In the SI system, A has the numerical value 4.50 and B has the numerical value 8.75
(a) What are the SI units of A and B?
(b) What impulse does this force impart to the object?
What will be an ideal response?
Answer: (a) A: N/s4 = kg ? m/s6 , B: N/s2 = kg ? m/s4 (b) 12.9 N ? s, horizontally
