Pad 6:24 PM * 94% a flipitphysics.com Walk-Thru: Stop the block Standard Exercse Stretching Spring For assistance with this problem, see Example 13-6. Mass on Spring Standard Exercse Simple Pendulum Standard Exercse Graph of an Oscillator Standard Exercse Gum hits Pendulum Standard Exercise Graduate Student Car Real Spring Standard Exercke Walk-Thru: Stop the bloc Standerd Exercise Attributes of an Oscillato A 1.52 kg block slides on a frictionless, horizontal surface with an speed of 1.35 m/sec. The block encounters an unstretched spring with a spring constant of 255 N/m. 1) What is the initial kinetic energy of the block before it hits the spring? KEo J Submit 2) What is the potentil energy of the mass and spring system when the spring is at its point of maximum compression? Umax JSubrnit 3) How far is the spring compress before the block comes to rest? meters Submit 4) If the mass and block were to oscillate, what would be the period of the oscillation? seconds Submit 5) How long is the block in contact with the spring before it comes to rest? seconds Submia

Explanation / Answer

1] KE0 = 0.5 mv^2 = 0.5*1.52*1.35^2 = 1.3851 J

2] Umax = 1.3851 J by energy conservation

3] 0.5 kA^2 = Umax = 1.3851

A = sqrt(2*1.3851/255) = 0.104 m

4] T = 2pi* sqrt(m/k) = 2pi*sqrt(1.52/255) = 0.485 s

5] t = T/4 = 0.485/4 =  0.121 s
