(13%) Problem 3: A teenager of mass m1-52 kg pushes backwad against the ground with his foot as he rides his This exerts a horizontal force of magntude Foo,-19 N The skateboard has m2-2. I Randomized Variables m,-52 kg @ 25% Part (b) Choose the correct free-body diagram for the system made up of teenager and his skateboard FN is the normal force and F is the weight of the teenager and the skateboard a> a 25% Part (c) write an expression in terms ofgiven quantities for the magnitude pleted pushing backwards on the ground. Grade Summary Potential 100% Submissions Attempts remaining S 0% per attempt) detailed vie pleted 1 2 3 Hist Hints:--deduction per hint. Hints remaining:- in m/sExplanation / Answer
here,
Ffoot = 19 N
m1 = 52 kg
m2 = 2.1 kg
c)
the magnitude of accelration , a = net force /effective mass
a = Ffoot /(m1 + m2)
d)
a = 19/( 52 + 2.1) m/s^2
a = 0.35 m/s^2
