Hello,

Would someone let me know if my math is displayed properly? (like m s x m s = 1) or kg etc. Are they in the right place? I'm not worried about the values. Thank you

Knowing that the initial vertical speed, u = 0 m s but now that free fall is happening, the lander will experience acceleration at g: =4.36 m s2 (from above equation) along vertically downward direction. knowing from kinematics, v = u + gt, and time of fall, t: =300s and v: =0+4+436ms? =436ms?x300s =5/ s =i = 1308 ms or ~ 131 m s (in 3 sig-fig) Therefore, the vertical speed of the lander after 300 seconds is approximately 131 m s in three significate figures
