Answer #1

Q1

By linear momentum conservation , take sled direction as positive

Pi = Pf

M_total *V = m_rock*V_rock + m_sled+man * V_sled+man

(97.5) *0.490 = 0.320*17 +( 97.5-0.320) *V_sled+man

V_sled+man = [ (97.5) *0.490 - 0.320*17 ] / ( 97.5-0.320)

=0.435635 m/s

Q2

if rock thrown in opposite direction

Pi = Pf

M_total *V = m_rock*V_rock + m_sled+man * V_sled+man

(97.5) *0.490 = -0.320*17 +( 97.5-0.320) *V_sled+man

V_sled+man = 0.547592 m/s

    A boy sleds down a hill and onto a frictionless ice-covered lake at 14.4 m/s. In the middle of the lake is a 1,000 kg boulder. When the sled crashes into the boulder, he is propelled over the boulder and continues sliding over the ice at 14.4 m/s. If the boy's mass is 40.0 kg and the sled's mass is 13.0 kg, what are the speeds (in m/s) of the sled and the boulder after the elastic collision? (Due to...
