For the gravitational force the formula<span> is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s</span>2<span> at the surface of the earth) and h is the </span>height<span> in meters. Notice that gravitational potential </span>energy<span> has the same units as </span>kinetic energy, kg m2<span> / s</span>2<span>.

Answer:
Total distance traveled= 75.36km (point at which she reaches her destination.)
Explanation:
With the speed and time data we can calculate the distance traveled on each path, but first we must transform the time units from minutes to hours:
First ride:
v=80km/h t=25min*1h/60min=0.42h
distancie= v*t = 80km/h * 0.42h =33.6km
Second ride:
v=65.0km/h t= 20min*1h/60min= 0.33h
distance= 65.0km/h*0.33h=21.67km
Stop: 60min= 1h distance=0km
third ride:
v= 40.0km/h t= 30.0min *1h/60min= 0.5h
distance= 40.0km/h*0.5h=20km
Total distance traveled= 33.6km +21.76km+20km
Total distance traveled= 75.36km
Answer:
In my physics class, something that helps connect better with kids is keeping connected with them always make sure to ask if they understand what you're teaching if they are following because sometimes most kids are to afraid to admit that they are lost, another way to connect with kids is maybe posting surveys to be able to check in with each student especially during this hard times :)
Explanation:
Neither the opposite direction (left) or its slowing down. Hope this helps
