A bullet with mass m = 40 grams traveling at v = 400 m/s strikes a block of wood suspended from a ceiling with a massless cord. The collision last for 15 milliseconds, and after it is completed the bullet embeds itself into the block. Then, the combined system rises to a maximum height has its swings upward as shown. The mass of the wooden block is M=5.0kg and the length of the cord is L = 1.25 m. Calculate...
A bullet of mass 0.056 kg traveling horizontally at a speed of 100 m/s embeds itself in a block of mass 1.5 kg that is sitting at rest on a nearly frictionless surface. (a) What is the speed of the block after the bullet embeds itself in the block? v= m/s (b) Calculate the kinetic energy of the bullet plus the block before the collision: K; = (c) Calculate the kinetic energy of the bullet plus the block after the...
A bullet of mass 0.017 kg traveling horizontally at a high speed of 210 m/s embeds itself in a block of mass 4 kg that is sitting at rest on a nearly frictionless surface. (a) What is the speed of the block after the bullet embeds itself in the block? Vf = m/s ) Calculate the total translational kinetic energy before and after the collision. Ktrans,i = Ktrans,f = (c) Compare the two results and explain why there is a...
A bullet of mass 0.017 kg traveling horizontally at a high speed of 210 m/s embeds itself in a block of mass 5 kg that is sitting at rest on a nearly frictionless surface. (a) What is the speed of the block after the bullet embeds itself in the block? Vr = 42 x m/s (b) Calculate the total translational kinetic energy before and after the collision. Ktrans,i = 374.85 Ktrans,f= (c) Compare the two results and explain why there...
A 27-g rifle bullet traveling 200 m/s embeds itself in a 3.9-kg pendulum hanging on a 2.6-m-long string, which makes the pendulum swing upward in an arc. Determine the vertical component of the pendulum's maximum displacement. Determine the horizontal component of the pendulum's maximum displacement.
A 28-g rifle bullet traveling 170 m/s embeds itself in a 3.9-kg pendulum hanging on a 2.8-m-long string, which makes the pendulum swing upward in an arc. (Figure 1) Determine the vertical component of the pendulum's maximum displacement. Determine the horizontal component of the pendulum's maximum displacement.
Problem 35 35. (II) A 28-g rifle bullet traveling 190 m/s embeds itself in a 3.1-kg pendulum hanging on a 2.8-m-long string, which makes the pendulum swing upward in an arc. Determine the vertical and horizontal components of the pendulum?s maximum displacement.
A bullet with some mass, m, and initial speed, vi, collides with a wooden block of mass M that is hanging at the end of a light rope. The bullet imbeds itself in the block and the block and bullet swings upwards reaching a maximum height of h above the initial point of the collision. a. A scientist can measure the masses and the height, show that the initial speed can then be calculated from the following equation: vi= (m+M)/m×root...
Forensic scientists can determine the speed at which a rifle fires a bullet by shooting into a heavy block hanging by a wire. As the bullet embeds itself in the block, the block and embedded bullet swing up; the impact speed is determined from the maximum angle of the swing (a) Which would make the block swing higher, a 0.204 Ruger bullet of mass 2.14 g and muzzle speed 1290 m/s or a 7-mm Remington Magnum bullet of mass 9.71...
A rubber bullet of mass m = 0.025 k g m=0.025kg traveling at velocity v 0 = 50 m / s v 0 =50m/s hits an iron block of mass M = 15 k g M=15kg initially hanging at rest from a massless rope. After the collision, the bullet bounced straight back at a velocity of v 1 = 35 m / s v 1 =35m/s. The effect of gravity on the bullet alone can be ignored. To...
