Answer:
80km/hr
Explanation:
Total distance: 400km
Total time 5 hours
Average speed= distance/time
400/5= 80km/hr
Answer:
Because psuedoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
And it is most of the time false
Explanation:
1 newton =
the force that accelerates 1 kilogram of mass at the rate of 1meter per sec²
1 N = 1 kg-m/s²
1. V = Vo + a*t.
<span>15 = 0 + a*5 a = 3 m/s^2. </span>
<span>2. V = Vo + a*t. </span>
<span>0 = 15 - 5*t, t = 3 s. </span>
<span>3. d1 = Vo*t + 0.5a*t^2. </span>
<span>Vo = 0, t = 5, a = 3 m/s^2, d1 = ?. </span>
<span>d2 = Vo*t. Vo = 15 m/s, t = 15 s, </span>
<span>d2 = ?. </span>
<span>V^2 = Vo^2 + 2a*d3. </span>
<span>V = 0, Vo = 15 m/s, a = -5 m/s^2, d3 = ?. </span>
<span>d1+d2+d3 = Total dist.</span>
