Answer:
48m
Explanation:
Given the following data;
Initial velocity = 0m/s
Final velocity = 6m/s
Time, t = 6 secs
Time, T2 = 5 secs
Mathematically, acceleration is given by the equation;
Substituting into the equation;
Acceleration, a = 1m/s²
<u>To find the distance covered in the first phase;</u>
<em>Solving for distance, we would use the second equation of motion;</em>
<em>Substituting the values into the equation;</em>
Distance, S1 = 18m
<u>For the second phase, time T2 = 5 secs;</u>
<em>Mathematically, speed is given by the equation;</em>
<em>Making distance the subject of formula, we have;</em>
<em>Substituting into the above equation;</em>
Distance, S2 = 30m
Total distance = S1 + S2 = 18m + 30m = 48m
Total distance = 48m
<em>Therefore, the total distance traveled by the biker is 48m.</em>
Answer:
<em>About four million tons of </em><em><u>matter</u></em><em> are converted to energy in the Sun’s core every second</em>
Explanation:
<u>The Sun </u>
It's estimated that The Sun fuses near 600 million tons of hydrogen into helium every second. As a result, 4 million tons of matter are converted to energy every second according to Einstein's equation
