E 15. A string is now attached to the block and it is pulled up the incline ( the string is parallel to the incline surface) with a tension force of 40 N. The block slides up at a coefficient of kinetic friction between the incline and block is a) 0.53 b) 0.58 c) 0.63 d) 0.68 e) more information is needed to determine speed of 1.5 m/s. The VES 40N
2.) A bullet (15g) traveling with an initial speed of 500 m/s passes through a block (800g) initially at rest. A) What is the final speed of the block if the bullet is now traveling with a speed of 420 m/s after it has exited the block (assume there is no loss of mass for the block when the bullet passes through the block)? (5pts) 500 m's 420 m/s Before Collision After Collision B) Since this is an inelastic collision,...
A thin block of soft wood with a mass of 0.072 kg rests on a horizontal frictionless surface. A bullet with a mass of 4.67 g is fired with a speed of 581 m/s at a block of wood and passes completely through it. The speed of the block is 16 m/s immediately after the bullet exits the block. Determine the speed of the bullet as it exits the block. m/s
If a bullet with a mass of 4.2 g and a speed of 650 m/s is fired at a block of wood with a mass of 9.8×10−2 kg . The block rests on a frictionless surface, and is thin enough that the bullet passes completely through it. Immediately after the bullet exits the block, the speed of the block is 21 m/s . A) What is the speed of the bullet when it exits the block? B) Verify Kf<Ki calculating...
A thin block of soft wood with a mass of 0.070 kg rests on a horizontal frictionless surface. A bullet with a mass of 4.67 g is fired with a speed of 629 m/s at a block of wood and passes completely through it. The speed of the block is 25 m/s immediately after the bullet exits the block.

A 0.30-kg block rests on a frictionless level surface and is attached to a horizontally aligned spring with a spring constant of 52.0 N/m. The block is initially displaced 3.20 cm from the equilibrium point and then released to set up a simple harmonic motion. What is the speed of the block when it passes through the equilibrium point?
A bullet of mass m is moving horizontally with speed vo when it hits a block of mass 100m that is at rest on a horizontal frictionless table. The surface of the table is a height h above the floor The bullet passes through the block at a speed of 1/2 vo Derive an expression for the velocity of the block immediately after the collison (before leaving the table) in terms of m and vo
A 5.00-g bullet moving with an initial speed of 450 m/s passes through a 1.00-kg block, as shown in the figure. The block is initially at rest on a frictionless, horizontal surface and is connected to a spring that has a spring-force constant of 900 N/m. The block moves a distance d = 3.34 cm to the right after the collision. Note that the block only starts moving after the bullet has completely passed through the block. IWW d Round...
A block of mass M = 0.400 kg is attached to a spring that initially rests on a frictionless, horizontal surface. A moving rifle bullet with mass m = 16.0 g strikes and embeds itself in the block. The impact compresses the spring by 28.0 cm. The spring constant of the spring is k = 455 N/m. What was the initial speed of the bullet?
