On Earth, the acceleration due to gravity is (-9.8 meters per second) per second.
If the school, the roof, and the pencil are on Earth,
then after 3 seconds, the pencil's speed is
[ (-9.8 meters per second)/second ] times [ 3seconds ] = <u>-29.4 meters per second </u>
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
Answer:
mass X velocity
Explanation:
The momentum of a body is the product of its mass and velocity
