Aperson (mass m1=70 kg) is climbing a ladder (length l=6m, mass m2=20kg) that leans against a smooth wall (no friction between wall and ladder). a frictional force fs between the ladder and the floor keeps it from slipping. the angle between the ladder and the wall is 30. – what is the magnitude of fs so that the person can reach the top of the ladder

with 5 seconds, no, but over time if the police car stays at 65m/s ad the speeding car stays at 60, then obviously yes, but the answer to your question would be, no.

hope this : )

if i am correct, your answer choices are:

a. the temperature remains constant

b. the temperature increases at a constant rate

c. heat flows at a constant rate into the system

d. heat flows at a constant rate out of the system

e. no heat flows into or out of the system

if so, then the answer is e. no heat flows into or out of the system.
