False. You don’t want to over work yourself :) start at a level you are comfortable with and continue with making it more and more harder. EX: you can run around your block and you feel tired but refreshed. Do it everyday until you feel like you can go further
Answer:
12.72 sec
Explanation:
The time it takes to travel a certain distance can be found by dividing the distance that needs to be travelled by the speed with which you are travelling, therefore...
Let x be the speed of the slower car and that x + 20 be the speed of the faster car. The time it takes for the object to travel a certain distance is the quotient when distance is divided by the speed.
t = d / S
Substituting the given and equating their times,
t = 225 / (x + 20) = 165 / x
The value of x is equal to 55. Therefore, the value of t is equal to 3 hours.
Considering that Work, W, is:
W=F·d
You have: 224=F·32
So that F=7 N
