A projectile is launched with an initial speed of 50.0 m/s at an angle of 35.0" above the horizontal. The projectile lands on a hillside 3.5 s later. Neglect ar fretion. (Assume that the treats is to the right and the +y-axis is up along the page.) (a) What is the projectile's velocity at the highest point of its trajectory? magnitude m/s direction counterclockwise from the x- (b) What is the straight-line distance from where the projectile was launched to where it hits its target?
