Answer:
8.95 m/s
Explanation:
(3.5-1.0) x 2 = gt²
t = √5/9.8 = 0.714 sec
= X/t = 4/ 0.714 = 5.602 m/s
vertical velocity means it has to rise 1.0 m against gravity in 0.714s
= gt = 9.8 x 0.714 = 6.99 m/s
V = √²+ ² = √6.99²+5.602² = 8.95 m/s
The correct answer is erosion.
This drag force is always opposite to the object's motion, and unlike friction between solid surfaces, the drag force increases as the object moves faster.
