Robin would like to shoot an orange in a tree with his bow and arrow. The orange is hanging yf = 5.00 m above the ground. On his first try, Robin looses the arrow at v0 = 36.0 m / s at an angle of θ = 30.0 ° above the horizontal. The arrow has an initial height of y0 = 1.50 m, and its tip is x = 52.0 m away from the target orange. Treating the arrow as a point projectile and neglecting air resistance, what is the height of the arrow once it has reached the horizontal position x of the orange? Use g = 9.81 m / s 2 for the acceleration due to gravity.

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
