1>A flare is dropped from a plane flying over level ground at avelocity of 70 m/s in the horizontal direction. At the instant theflare is released, the plane begins to accelerate horizontally at0.75 m/s2. The flare takes 4.0 s to reach the ground. Assume airresistance is negligible. Relative to a spot directly under theflare at release, where does the flare land?
2>A projectile is fired from a gun near the surface of Earth.The initial velocity of the projectile has a vertical component of98 meters per second and a horizontal component of 49 meters persecond. How long will it take the projectile to reach the highestpoint in its path?
3>The diagram below shows a student throwing a baseballhorizontally at 25 meters per second from a cliff 45 meters abovethe level ground. Approximately how far from the base of the cliffdoes the ball hit the ground? Neglect air resistance. Use g = 9.8m/s2
