Answer: If i'm not mistaken I think it A) potential
7 and a half hours because if you multiply 120 by 8 you get 960 and if you multiply 120 by 7 you get 840. So it’ll take 7 full hours and 30 minutes to reach 950 km. Hope this helps and I’m sorry if it’s wrong I did my best :)
Answer:
Power = 56.25 W
Explanation:
Power = workdone/time taken
We are given;
Mass; m = 50 kg
Final velocity; v = 3 m/s
Time; t = 4 s
Workdone = ½mv² = 1/2 × 50 × 3²
W = 25 × 9
W = 225 J
Thus;
Power = 225/4
Power = 56.25 W
