a projectile travels in the horizontal direction at a velocity of 200.0 meters/second from a cliff that is 200.0 meters high. after how many seconds will the projectile reach the ground level? a. 4.2 seconds b. 6.2 seconds c. 6.4 seconds d. 9.2 seconds

Option (c) is correct.The projectile will reach the ground after a time of 6.4 seconds.

Explanation:

Height of cliff= 200 m

initial velocity along vertical=0

initial velocity of horizontal=200 m/s

we use the kinematic equation;

h= Vit +1/2 gt²

200=0(t) + 1/2 (9.8)t²

4.9t²=200

t²=40.82

t=6.4 seconds

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~

answer

the arrows to the right of earth should point up.
