Answer:
5km/h
Explanation:
The equation for average speed is
Vavg = Δd/Δt
where Δd is distance and Δt is time
from what's given, we know she travelled 15km in total and the trip took 3 hours in total. We can now plug in the values into the equation
Vavg = 15/3
Vavg = 5km/h
The particles are making no motion at all.
Q.1
Answer . Momentum = mass x velocity
Momentum/mass = velocity
5/0.8 = velocity
6.25 m/s = velocity
Q.2
Answer . F = ma => a = f/m => a = 7/3.2 => a = 2.1875m/s²
