Respuesta :
153 miles x 5280 feet per mile = 807,840 feet per hour.
1 hour = 3600 seconds.
The speed is 807,840 feet / 3600 = 224.4 feet per second.
Distance in 15 seconds = 224.4 x 15 = 3,366 feet.
The height of the rocket after t seconds is given by the equation h(t) = -16t² + 42t
What is an equation?
An equation is an expression that shows the relationship between two or more variables and number.
1 mile = 5280 feet, 1 hour = 3600 seconds
153 miles per hour = (153 * 5280) / (3600) ft/s = 224.4 ft/s
After 15 seconds, height = 224.4 ft/s * 15 s = 3366 ft
The speed of the parachute is 224.4 ft/s, while after 15 seconds the distance fell was 3366 ft.
