A ball is thrown upward from the ground with an initial speed of 20.8 m/s; at the same instant, a ball is dropped from rest from a building 11 m high.

A ball is thrown upward from the ground with an initial speed of 20.8 m/s; at the same instant, a ball is dropped from rest from a building 11 m high.

A ball is thrown vertically upward from the top of a building 32 feet tall with an initial velocity of 16 feet per second. The distance s (in feet) of the ball from the ground after t seconds is s=32+16t-16t^2. a. after how many seconds does the ball strike the ground? set s to zero and solve for t: s=32+16t-16t^2 0=32+16t-16t^2 0=2+t-t^2 t^2-t-2=0

A ball is thrown upward from the edge of a building that is 100 m tall. On its way back down, the ball just misses the building, falling to the ground below.

A ball is thrown upward with an initial velocity of 9.81 m/s from the top of a building. a. Fill in the table below showing the ball's position, velocity, and'/ acceleration at the end of each of the first 4 s of motion.

A ball is thrown vertically upward from the top of a building 144 feet tall with an initial velocity of 128 feet per second. The distance s (in feet) of the ball from the ground after t seconds is s=144+128t-16t^2 After how many seconds does the ball strike the ground? After how many seconds will the ball pass the top of the building on its way down?
