Question

• always use significant figure rules. remember that these rules apply to all numbers that are measurements.

a missile is fired from a jet flying horizontally at mach 1 (1100 ft/s). the missile has a horizontal acceleration of 1000 ft/s². calculate its horizontal velocity at 10.0 seconds after it is fired. (assume constant acceleration of the missile throughout its flight.)
1,220,000 ft/s
11,100 ft/s
11 00 ft/s
12 00 ft/s

Explanation:

Step1: Identificar la ecuación de movimiento

Utilizamos la ecuación $v = v_0+at$, donde $v$ es la velocidad final, $v_0$ es la velocidad inicial, $a$ es la aceleración y $t$ es el tiempo.

Step2: Sustituir valores dados

Tenemos $v_0 = 1100$ ft/s, $a = 1000$ ft/s² y $t = 10.0$ s. Entonces $v=1100 + 1000\times10.0$.

Step3: Realizar el cálculo

$v=1100+10000=11100$ ft/s.

Answer:

11,100 ft/s
