A classic physics problem states that if a projectile is shot vertically up into the air with an initial velocity of 146 feet per second from an initial height of 89 feet off the ground, then the height of the projectile, h, in feet, t seconds after it's shot is given by the equation: h=−16t2+146t+89h=-16t2+146t+89 Find the two points in time when the object is 126 feet above the ground (to one decimal places). Answer: The object is 126 feet off the ground at the following times: (Enter your two answers separated by a comma. Round to ONE decimal places.)
Use the position function s(t) = −4.9t2 + 250, which gives the height (in meters) of an object that has fallen for t seconds from a height of 250 meters. The velocity at time t = a seconds is given by as attached. When will the object hit the ground? At what velocity will the object impact the ground?
A rocket ship has a position given by x(t)=bt2 meters. In order for it to reach a velocity of 5,000 m/s in 40,000 meters, what must be the value of b?
On a planet very similar to Earth, but slightly denser, where acceleration due to gravity is 10 m/s2, a projectile is fire vertically from a height of 100 meters with an initial velocity of 40 m/s. Its position above the ground after t seconds is given by h(t) = 100 + 40t − 5t2 meters. Find the maximum height the projectile attains.
Consider A runner moving in a positive direction with an initial velocity of 4.6 m/s slows down at a constant rate of -1.3 m/s squared over a period of 2 seconds. What distance does she travel during this process?
On a planet very similar to Earth, but slightly denser, where acceleration due to gravity is 10 m/s2, a projectile is fire vertically from a height of 100 meters with an initial velocity of 40 m/s.

A kangaroo jumps straight up to a vertical height of 1.15 m How long was it in the air before returning to Earth?
If a ball is thrown upwards with velocity V1, maximum height attained by the ball is H1, if ball is thrown with V2 = 3V1, what will be the new maximum height?
The range of a projectile depends not only on v0 and but also on the value g of the free-fall acceleration, which varies from place to place. In 1936, Jesse Owens established a world’s running broad jump record of 8.09 m at the Olympic Games at Berlin (where g 9.8128 m/s2). Assuming the same values of v0 and , by how much would his record have differed if he had competed instead in 1956 at Melbourne (where g = 9.7999 m/s2)?
A person walks up a stalled 15-m-long escalator in 90 s. When standing on the same escalator, now moving, the person is carried up in 60 s. How much time would it take that person to walk up the moving escalator? Does the answer depend on the length of the escalator?
