Amodel jet is fired up in the air from a 16-foot platform with an initial upward velocity of 52 feet per second. the height of the jet above ground after t seconds is given by the equation h=-16t^2+52t+16, where h is the height of the jet in feet and t is the time in seconds since it is launched. approximately how long does it take the jet to reach its highest point? a. 0.3 seconds b. 1.6 seconds c. 3.3 seconds d. 6.5 seconds

option B

h=-16+52t+16

where h is the height of the jet in feet and t is the time in seconds since it is launched.

We need to find the time taken to reach the maximum height.

Highest point is the vertex of the given equation.

To find the x coordinate of vertex we use a formula

t =

From the given equation

h=-16+52t+16

a= -16 , b= 52, c= 16

Plug in the values in the formula

t =

t =

t= 1.625 seconds

Approximately t= 1.6 seconds

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
