Answer: A, B, F
Explanation:
Answer: Acceleration =5m/s^2
Answer:
3.962
mass = 1.2
gravity g = 9.81
velocity = ?
mgh = 1/2mv² + 1/2(1/2)mv²
= 9.81 x 1.2 = 3/4v²
11.772 x 4 = 3/4v²
47.088 = 3v²
divide through both sides by 3
15.696 = v²
take the square root of both sides
√15.696 = √v²
= 3.6962 = v
the speed is therefore 3.692
