A 3 kg object travelling to the right at 8 m/s collides with a 6 kg object travelling to the left at 9 m/s. After the collision, the second object is travelling to the right at 10% of its original speed. What is the final velocity of the first object?
3. A block of mass m = 6.2 kg, moving on a frictionless surface with a velocity of -6.5 m/s to the right, collides with a block of mass M at rest, as shown in the figure. After the collision, the 6.2-Kg block recoils with a velocity of f =0.70 m/s to the left. If the blocks are in contact for 0.30 s, what is the magnitude of the average force on the 6.2-kg block, while the two blocks are...
A 9 kg object travelling 6 m/s to the right collides elastically with a 5 kg object travelling to the left at 9 m/s. What is the ratio of the final velocity of object 2 to object 1 after the collision? *Keep in mind the answer is supposed to be negative*
A 0.5 kg ball bounces off a wall. The magnitude of the velocity is 4 m/s both before it hits the wall and right after. If the ball was in contact with the wall for 5 m/s, what was the average force exerted on the ball? A. -800 B. 800 C. -8x10^-4 D. 8x10^-4
A 3.5 kg block with a speed of 3.6 m/s collides with a 7.0 kg block that has a speed of 2.4 m/s in the same direction. After the collision, the 7.0 kg block is observed to be traveling in the original direction with a speed of 3.0 m/s. (a) What is the velocity of the 3.5 kg block immediately after the collision? (b) By how much does the total kinetic energy of the system of two blocks change because...
A block having a mass of 0.800 kg is given an initial velocity vA= 1.25 m/s to the right. It collides head-on with a horizontal spring of negligible mass and force constant k = 50 N/m, resting on the table. (a)Assuming the surface to be frictionless, calculate the maximum compression of the spring after the collision. Assume that the block gets stuck to the spring. (b)Suppose a constant force of kinetic friction acts between the block and the surface, with...
A 5.00 kg frictionless puck travelling at 8.00 m/s collides with another of mass 3.0 kg which is travelling in the same direction at 4.0 m/s. They remain stuck together after the collision : What is their speed after the collision?
A 6.9 kg block with a speed of 4.8 m/s collides with a 13.8 kg block that has a speed of 3.2 m/s in the same direction. After the collision, the 13.8 kg block is observed to be traveling in the original direction with a speed of 4.0 m/s. (a) What is the velocity of the 6.9 kg block immediately after the collision? (b) By how much does the total kinetic energy of the system of two blocks change because...
A 2-kg block moving in the positive x direction with a speed of 5.0 m/s collides with a 3-kg block moving in the same direction with a speed of 2.0 m/s. After the collision the 3-kg block moves at 4.2 m/s. Find the velocity of the 2-kg block after the collision. Is the collision elastic or inelastic? Justify your answer.
) A 2000 kg truck is going 20 m/s collides with a brick wall bringing it to a stop. The truck is totaled, but the wall is fairly undamaged. If the collision lasts 100ms, find the average force exerted on the truck by the brick wall. How does this compare to the force that the truck exerts on the wall?
