6. .A 1.00-kg object is attached to a horizontal spring. The spring is initially stretched by 0.100 m, and the object is re- leased from rest there. It proceeds to move without fric- tion. The next time the speed of the object is zero is 0.500 s later. What is the maximum speed of the object?

A 4 kg object is released from rest from a height of 1.2 m above a vertical spring (initially in its natural state). The object strikes the top end of the spring compressing it at distance of 0.6 m. Find the spring's force constant.   A.) 261.33 N/m B.) 366.25 N/m C.) 480.00 N/m D.) 164.64

QUESTION 4 A block with a mass M=1 kg is attached to a spring with a spring constant k=100 N/m, stretched 0.1 m and released. What is the maximum velocity of the block? 0 0 0 0 О 1 m/s 10 m/s 20 m/s 50 m/s 100 m/s

X Incorrect The 14.9-in.spring is compressed to a 7.6-in. length, where it is released from rest and accelerates the sliding block A. The acceleration has an initial value of 440 ft/sec² and then decreases linearly with the x-movement of the block, reaching zero when the spring regains its original 14.9-in. length. Calculate the time t for the block to go (a) 3.65 in. and (b) 7.3 in. -7.6 14.9 Answers: To go 3.65 in., t= i To go 7.3 in., t= 0.017 0.012 sec sec
