Question

8 of 13 (Figure 1) depicts the potential energy of a 350-kg palet that slides from rest down a Part A ramp, then moves across a spring at ® 4.0 m. When the pallet encounters the spring, it momentarily comes to rest at What is the force constant of the spring? 6.0 m Figure 1011 alue Units 3000 Spring potential energy 2500 Gravitational potential energy 2000 1500 1000 500 - Part B At what height h above the horizontal conveyer did the pailet begin siding from rest? Express your answer to two significant figures and include appropriate units. 2 3 45 67 Value Units Position, x (m) MacBook Air

Explanation / Answer

(a) when compression is 2m,energy=1000J

0.5*K*x^2=1000

We got

K=500 N/m

(b)

Let the height is h

mgh=2500

350*9.8*h=2500

h=0.73 m
