You are target shooting using a toy gun that fires a small ball at a speed of 15 m/s. When the gun is fired at an angle of 33 ∘ above horizontal, the ball hits the bull's-eye of a target at the same height as the gun. Then the target distance is halved.

At what angle must you aim the gun to hit the bull's-eye in its new position?

Astone is dropped from the upper observation deck of a tower, 250 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t. h(t) = (b) how long does it take the stone to reach the ground? (round your answer to two decimal places.) s (c) with what velocity does it strike the ground? (round your answer to one decimal place.) m/s (d) if the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (round your answer to two decimal places.) s
