Answer
given,
time interval = 11.3 s
a) initial velocity, vi = 15 m/s
final velocity, v_f = -5.30 m/s
a = -1.79 m/s²
the direction is along left side
b) initial velocity, vi = -5.30 m/s
final velocity, v_f = -15 m/s
a = -0.858 m/s²
the direction is along left side
c) initial velocity, vi = 15 m/s
final velocity, v_f = -15 m/s
a = -2.65 m/s²
the direction is along left side
Since momentum is a vector quantity, take any direction as positive and other as negative. Answer won't change.
Answer:
Explanation:
Force = (mass) · (acceleration)
= (1,000 kg) · (9.8 m/s²)
= 9,800 newtons
Let us first write down the known things .
1660 megawatts = 1660 X 10^6 watt
= 166000 kilowatt
From the above deduction we can conclude that the correct option among all the options that are given in the question is the second option or option "B". I hope that this is the answer that you were looking for and the answer has actually come to your desired help.
30 km (20 mi) to 50 km (30 mi)
