A projectile is launched with an initial speed of 40 m/s at an angle of 25 above the horizontal. The projectile lands on a hillside 3 s later. Neglect air friction. (a) What is the projectile's velocity at the highest point of its trajectory? m/s (b) What is the straight-line distance from where the projectile was launched to where it hits its target? (Note that the hill may slope up or down from the launch point.) m
