A 9.0-g bullet is fired into a 160-g block of wood at rest on a horizontal surface. After impact, the block slides 7.80 m before coming to rest. If the coefficient of friction between the block and the surface is 0.430, what is the speed of the bullet before impact?
A 9.1 g ball is hit into a 98 g block of clay at rest on a level surface. After impact, the block slides 8.0 m before coming to rest. If the coefficient of friction is 0.60, determine the speed of the ball before impact. (Answer: 33m/s)
A3 g bullet is fired horizontally into the 0.5 kg block which rests on the rough surface coefficient of friction 01. Alter the bullet becomes embedded into the book, the block moves to the night 03 m before momentarily coming to rest Determine the speed (b) of the bullet. The spring has a stress 200-Num and is ongly un stretched [m/s] k = 200 N/m WWWWW
Problem 2 A 1.0 kg cannonball is fired horizontally with a speed of 200 rn/s at two blocks (each with mass 10.0 kg at rest on a frictionless surface). The ball embeds itself in the first block, and then the ball and block 1 traveling together collide elastically with block 2. All external forces are negligible compared with the net explosion or collision forces. Use the reference frame provided. Neglect the material removed from the block during collision with the...
. A 2.00kg block is moved from point A (at rest) a distance of 2.00 m to point B under the action of a variable force F(x) 10x + 6x2. Once in point B it is moving down 1.00 m through an 60.00 inclined frictionless surface until hit a spring (point C) as shown in figure. (The coefficient of kinetic friction between the block and the surface between A and B is 0.3 and the spring constant equal to 400...
Incline, Spring, and Friction: A block of mass 500 g is attached to a spring of spring constant 80 N m−1. The other end of the spring is attached to a support while the mass rests on a rough surface with a coefficient of friction of 0.20 that is inclined at angle of 30◦ . The block is pushed along the surface till the spring compresses by 10 cm and is then released from rest. (a) Compute how much potential...
can someone solve all parts please The 30 kg mass has a speed of 2m/sec in the position shown and a constant force of 20N is applied on it as shown and this force is acting on the mass for another 3 meters down the incline and then disappears. After another 7 meters the mass hits a loss of energy at impact to spring and Dynamic Friction coefficient is 0.25 Spring Constant is 200 kN/m A) What is the speed...
Problem 1: A car of mass 1000 kg moves at a constant speed of 20 m/s along a horizontal road where a frictional force is 200N. Calculate the power developed by the engine. If the car now moves up an incline at the same constant speed, calculate the new power developed by the engine. Assume that the frictional force is still 200 N and that sin(theta)=1/20 where theta is the angle of the incline to the horizontal. Problem 2: An...
Not A 5.00-g bullet moving with an initial speed of v 410 m/s is fired into and passes through a 1.00-kg block as shown in the figure below. The block, initially at rest on a frictionless, horizontal surface, is connected to a spring with force constant 940 N/m. The block moves d-5.60 cm to the right after impact before being brought to rest by the spring (a) Find the speed at which the bullet emerges from the block 146 your-esponse...
Please draw any relevant free body diagrams. Question 5 900 m/s The 200-g projectile is fired with a velocity of 900 m/s towards the center of the 15-kg wooden block, which rests on a rough surface. If the projectile penetrates and emerges from the block with a velocity of 300 m/s, determine the velocity of the block just after the projectile emerges. How long does the block slide on the rough surface, after the projectile emerges, before it comes to...
