Answer:
Kinematic equation Vf=Vo +a*t
Explanation:
in meters per second
V=9.8 * 4
V= 39.2 m/s
Answer:
What grade?? I’m not sure if this will help for your grade.
Explanation:
Multiply the time by the acceleration due to gravity to find the velocity when the object hits the ground. If it takes 9.9 seconds for the object to hit the ground, its velocity is (1.01 s)*(9.8 m/s^2), or 9.9 m/s.
