A projectile is launched at an angle of 45° from the horizontal and lands 21 s later at the same height from which it was launched. (a) What is the initial speed of the projectile (in m/s)? m/s (b) What is the maximum altitude (in m)? m (c) What is the range (in m)? m (d) Calculate the displacement (in m) from the point of launch to the position on its trajectory at 14 s. (Express your answer in vector form. Assume the projectile initially travels in the +x and +y-directions, where the +x-direction is horizontal and the +y-direction is straight up.) Δr = m
