A ball is projected horizontally from the top of the building of height 50 m with a horizonatal velocity of 4m/sec. What is the range of the ball? (physics)

12.78metres

Explanation:

it is a falling body projectile motion that Range

R = VoCosøt but ø= 0 no angle

R = Vot

and t is given by Newton's second eqn as

t=√(2h/g)

thus R=Vo√(2h/g)

upon substitution

R= 12.78

answer: a ball

explanation: because it will bounce

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
