Question

A projectile is launched with an initial speed of 44.0 m/s at an angle of 31.0° above the horizontal. The projectile lands on a hillside 3.60 s later. Neglect air friction. (Assume that the +x-axis 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-axis

(b) What is the straight-line distance from where the projectile was launched to where it hits its target?
