Answer:
The acceleration (a) is the gravitational constant (g), so 9.81 or 9.8 or 10 (9.81 in this case)
Final velocity:
Vf = vi (0 in this situation ) + gt
Vf = 9.8 * 260 (time in seconds)
Vf = 2548
(I am not sure why here it is 4.6, but since that is the only option after we answer the other two questions, it is.)
Height: Same formula as previous.
h = 1/2gt^2
h = 331240 meter (a lot) (I converted minutes to second by multiplying 4 my 60 + the other 20 sec) (The answer is a bit different because I used 9.8 as gravitational constant and they used 9.81)
