Two runners start at the same point on a straight track. the first runs with constant acceleration so that he covers 98 yards in 10 seconds. the second runner waited 5 seconds and then throws a rock at his opponent's head. of the head and the rock are at the same level form the ground, what must the initial magnitude of the velocity be if the rock is to hit the head just at the 98 yard tape? give the answer in feet per second.
