A projectile is launched with an initial speed of 80.0m/s at an angle of 40 degrees above the horizontal. The projectile lands on a hillside 3.80s later. Neglect air friction.

Question

What is the projectile's velocity at the highest point of its trajectory?

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

Answer 1

v= 61.3m/s at max h
straight line= 264.1m
