A projectile is launched with an initial speed of 40 m/s at anangle of 30° above the horizontal. The projectile lands on ahillside 4 s later. Neglect air friction.
(a) What is the projectile's velocity at the highest point of itstrajectory?
m/s
(b) What is the straight-line distance from where the projectilewas launched to where it hits its target? (Note that the hill mayslope up or down from the launch point.)
