Question

A braking thruster on a probe produces F(t)=(9t2−6t)F(t) = $$(9t^2 - 6t)  N $$for 1 s≤t≤4 s1	ext{ s} \le t \le 4	ext{ s}. What is the impulse over this interval?

Accepted Answer

144 N⋅s144	ext{ N}\cdot	ext{s}

Answer

108 N⋅s108	ext{ N}\cdot	ext{s}

Answer

192 N⋅s192	ext{ N}\cdot	ext{s}

Answer

48 N⋅s48	ext{ N}\cdot	ext{s}

A braking thruster on a probe produces F(t)=(9t2−6t)F(t) = (9t^2 - 6t) N for 1 s≤t≤4 s1\(\text{ s}\) \(\le\) t \(\le\) 4\(\text{ s}\). What is the impulse over this interval?

A braking thruster on a probe produces $F (t) = (9 t^{2} - 6 t)$ N for $1 s is less than or equal to t is less than or equal to 4 s$ . What is the impulse over this interval?
