Question #87b82 - Socratic See a solution process below: First, we need to determine how much was left before the man spent 20% We can rewrite this part of the problem as: 10200 is 80% of what? We are using 80% because he spent 20% so the man has 100% - 20% = 80% left "Percent" or "%" means "out of 100" or "per 100", Therefore 80% can be written as 80 100 When dealing with percents the word "of" means "times" or "to
Question #cebdb - Socratic The resultant vector shows the plane moving 528 16 kph bearing 65 9 degrees I always like to sketch out an idea of what we're looking at Let's resolve the vectors and find the x and y components * * * * * * * * * * * * * * * * * * * * * * * Vector A 500 kph 60 degrees We can find the y component using sin (theta)= (opp) (hyp) Lucky for us, we have hyp, 500, and theta, 60 sin (60)= (opp) 500
Question #b56ad - Socratic Explanation: Velocity of man just prior to landing on the pad #=4 4ms^-1# Momentum of man just prior to landing on the pad #p=mv# #=50xx4 4=220kgms^-1# Final velocity #=0# Change of momentum of man on his landing on the pad #=0-220=-220# From Newton's Second law of motion we know that Rate of change of momentum is the force applied #=-220 0 2
