The Answer of Impulse: 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?

Impulse: a Time-Varying Horizontal Force F(t) = At4 + Bt2

Impulse: a Time-Varying Horizontal Force F(t) = At⁴ + Bt²
