Answer:
100 m / s^
F =ma from this divided F and ma by m to get acceleration
a = F / m
a = ?
F = 5 N
m = 50 g = 0. 0 5 kg ; if 1 kg = 1000g how much kg of 50 g by criss cross method we get 0.05 kg
so; 5N / 0. 05 kg = 5kg m / s^ / 0.05 kg
kg cancel by kg
the result is 100 m/ s^
The Answer Second one , Plasma
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
