A fully compressed spring shoots a block up a 60 degree slope, given k = 1400N/m, m = 0.2kg, and ,Compressed = 0.1m. What is the max distance the block moves if: 1) There is no friction 2) Friction exists where =0.3

A block of mass m= 5.00 hg is released from piont A and slides down the frictionless track shown in the figure. calculate the sepeed of the block at piont B and C g= 9.8m/s2 .

A 20 kg box is released from rest on a friction incline of 40 degrees from the horizontal. 5 m down the incline there is a spring of spring constant 1500 N/m. How much does the box compress the spring before coming to rest?

A block of mass m = 2.80 kg is dropped from height h = 46.0 cm onto a spring of spring constant k = 986 N/m (see the figure). Find the maximum distance the spring is compressed. WI peeeeeeee

Figure (a) applies to the spring in a cork gun (Figure (b)); it shows the spring force as a function of the stretch or compression of the spring. The spring is compressed by 7.00 cm and used to propel a 3.90 g cork from the gun. (a) What is the speed of the cork if it is released as the spring passes through its relaxed position? (b) Suppose, instead, that the cork sticks to the spring and stretches it 1.70 cm before separation occurs. What now is the speed of the cork at the time of release? Force (N) 0.4 0.2 -4-2 2 4 -0.2 -0.4 (a) x (cm) Compressed spring. 0 (b) Cork

A 7.80-g bullet moving at 600 m/s penetrates a tree trunk to a depth of 4.50 cm. (a) Use work and energy considerations to find the average frictional force that stops the bullet. ____________________ N(b) Assuming the frictional force is constant, determine how much time elapses between the moment the bullet enters the tree and the moment it stops moving._____________________ s

A spring loaded toy dart gun shoots a dart straight up in the air and the dart reaches a maximum height of 22.90 m. The same dart is shot straight up a second time but this time the spring is compressed only half as far. How far up in meters does the dart go this time neglecting friction? Write your answer to 2 decimals. Your Answer: Answer
