h of t equals, negative 16, t squared, plus 48, t, plus 72 If air resistance is ignored, the function h defined above models the height above ground, in feet, of a toy rocket t seconds after it is launched from the roof of a building. Based on the model, what is the height above ground, in feet, of the toy rocket 1 second after launch?

Answer #1

Given function ,

If  air resistance is ignored, the function h defined above models the height above ground, in feet of a toy rocket t seconds after it is launched from the roof of a building .

so based on the model the height above ground 1 second after launch is ,

Hence ,

height above ground, in feet, of the toy rocket 1 second after launch is .

From the roof of the Empire State Building, you throw a coin up in the air and then watch it fall down, down, down to the street. The height of the coin (in feet) after tt seconds is given by h(t)=-16t^2+100t+1250h(t)=−16t2+100t+1250. After 12.512.5 seconds, the coin hits the street.

1.)You are hitting baseballs. When you toss the ball into the air, your hand is 5 feet above the ground (see figure). You hit the ball when it falls back to a height of 3.5 feet. You toss the ball with an initial velocity of 20 feet per second. The height h of the ball t seconds after leaving your hand is given by h = 5 + 20t ? 16t2. How much time will pass before you hit the...

A streamlined and compact projectile is launched from flat ground on a valley toward a distant hillside at an Army testing ground in Nevada. The projectile’s initial speed is vi = 150. m/s as it leaves the cannon. The initial angle of launch θi of the projectile is unknown. The projectile makes impact high on the distant hill a time t = 3.00 s after its departure. From GPS sensors we know that the site of impact is a straight-line...

A student throws a water balloon with speed v0 from a height h = 1.64 m at an angle θ = 29° above the horizontal toward a target on the ground. The target is located a horizontal distance d = 8.5 m from the student’s feet. Assume that the balloon moves without air resistance. Use a Cartesian coordinate system with the origin at the balloon's initial position. Part (a) What is the position vector, Rtarget, that originates from the balloon's...
