A 40.0 g bullet is fired at 100.0 m/s and embeds in a wooden block on asmooth surface frictionless surface. The block slides toward a horizontal spring,( k= 99.0 N/m). A maximum compression of 1.50 cm is observed. What is the mass ofthe block of wood? Draw a small diagram of the situation.

A block of mass 12 kg slides down a frictionless inclined plane inclined at 35° with no initial velocity and is stopped by a spring of k= 3.0 * 10^4 N/m. The block slides a total distance of d = 3 m from the point where it was released to the point where it stops due to the resistance of the spring. How much is the spring compressed when the block stops?

It will launch a 25 g projectile to a range of 2.15 m when it is launched at an angle of 45 degrees. You can use this information to find the initial velocity of the ball, of course, (and you should). Therefore, you should be able to calculate how much energy the spring in the projectile launcher must impart to the ball as it is being launched. The ball is pushed back 7.5 cm in the projectile launcher in order to getit ready to fire. What is the spring constant of the projectile launcher?

A spring with spring constant of 100 N/m launches a 20 g ball verticallyn into the air. If the ball reaches a height of 20 m, determine the original compression distance of the spring.

An object of mass 6.25 kg slides down a hill of height 21.1 m. At the bottom of the hill is a spring with spring constant 53.6 N/m. How far is the spring compressed when the mass comes to rest? Assume the mass starts from rest at the top of the hill. Give your answer in meters to three significant figures.

A block of mass m 2.00 kg slides along a horizontal table with speed vo 9.50 m/s. At x = 0 it hits a spring with spring constant k95.00 N/m and it also begins to experience a friction force. The coefficient of friction is given by u 0.100. How far has the spring compressed by the time the block first momentarily comes to rest? wwwww.wl Number 9.50 m/s m Ar ?
