A basketball player shoots toward a basket 5.3 m away and 3.0 m above the floor. If the ball is released 2.0 m above the floor at an angle of 60 above the horizontal, what must the initial speed be (in m/s) if it were to go through the basket? x m/s Additional Materials Reading A projectile is launched at an angle of 60 from the horizontal and lands 70 s later at the same height from which it was launched. (a) What is the initial speed of the projectile (in m/s)? 396.1 m/s (b) What is the maximum altitude (in m)? (c) 6002.5 m What is the range (in m)? 4340 x m (d) Calculate the displacement (in m) from the point of launch to the position on its trajectory at 62 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.) Ar = 4340m 15225.12m m
