) 7.20 min (C) 22.2 min (d) 12.5 min
1 answer:
Answer:
D. 12.5 min
Explanation:
Speed = distance ÷ time.
time = distance ÷ speed.
18km × 1000m = 18000m (as speed is in m/s).
time = 18000m ÷ 24.0m/s
t = 750s.
750s ÷ 60
= 12.5mins is your answer.

6. Drop to one quarter of its original value
F=MA
F=(8 kg)(9.8 m/s)
F= 78.4 N
W=FD
W=(78.4 N)(7 m)
