Answer:
The change in momentum of the car is 16380.8 kg.m/s
Explanation:
Given;
mass of the car, m = 1600 kg
time of motion, t = 4.20s
force of friction on the car, F = 3900 N
final velocity of the car after the brakes were applied, v = 0
The initial velocity of the car during the motion is calculated as;
The change in momentum of the car is calculated as;
ΔP = mu
ΔP = 1600 x 10.238
ΔP = 16380.8 kg.m/s
Answer:
No Time
Schedule activities into your day and use an exercise log so you can see how little time it takes.
Build activities into everyday tasks no matter where you are: Bike to work. Use the stairs. Take walk breaks at work. Garden. ...
Find an activity you enjoy that works for your schedule
