A 1.20-kg wooden block rests on a table over a large hole as in the figure below. A 5.25-g bullet with an initial velocity v, is fired upward into the bottom of the block and rem the collision. The block and bullet rise to a maximum height of 18.0 cm. M (a) Describe how you would find the initial velocity of the bullet using ideas you have learned in this chapter. (b) Calculate the initial velocity of the bullet from the information provided. (Let up be the positive direction. Indicate the direction with the sign of your answer.) m/s

A 70.0 kg ice hockey goalie, originally at rest, has a 0.280 kg hockey puck slapped at him at a velocity of 43.5 m/s. Suppose the goalie and the puck have an elastic collision, and the puck is reflected back in the direction from which it came. What would the final velocities ?goalie and ?puck of the goalie and the puck, respectively, be in this case? Assume that the collision is completely elastic.

Can you help me with this problem A 0.156 kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.900 m/sm/s. It has a head-on collision with a 0.291 kg glider that is moving to the left with a speed of 2.15 m/s Suppose the collision is elastic.Find the magnitude of the final velocity of the 0.156 kg glider in m/s. Find the magnitude of the final velocity of the 0.291 kg glider in m/s

Two objects collide head-on (see figure below). The first object is moving with an initial speed of  v1i = 8.09 m/s  and the second object is moving with an initial speed of  v2i = 10.00 m/s.  Assuming the collision is elastic,  m1 = 5.06 kg,  and  m2 = 6.18 kg,  determine the final velocity of each object. (Indicate the direction with the sign of your answer. Positive is to the right, and negative is to the left. Due to the nature of this problem, do not use rounded intermediate values in your calculations) v1f  =   m/s v2f  =   m/s

A car with a mass of 1000 kg traveling east at a speed of 25 m/s collides at an intersection with another car of 2000 kg traveling north at a speed of 20 m/s. Assuming that the vehicles stick together after the collision, calculate for: a. The direction of the wreckage after the collision. b. The magnitude of the velocity of the wreckage after collision

Use the worked example above to help you solve this problem. A car with mass 1.54 x 103 kg traveling east at a speed of 29.7 m/s collides at an intersection with a 2.47 x 103 kg van traveling north a speed of 17.2 m/s, as shown in the figure. Find the magnitude and direction of the velocity of the wreckage after the collision, assuming that the vehicles undergo a perfectly inelastic collision (that is, they stick together) and assuming that friction between the vehicles and the road can be neglected. 0.8 magnitude Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m/s direction 47.11 ° counterclockwise from the +x-axis

A light ball of mass 14.7g is at rest on table when a heavier ball of mass 26.3g and moving with an initial velocity of 2.01 m/s collides with but dosent stick to the first ball. After the collision, the lighter ball moves forward with a speed of 2.3 m/s. How fast will the heavier ball move after the collision. Give your answer in meter per second.

An 8-g bullet is fired horizontally to a wooden cube with a mass of 9 kg at rest. The bullet and wooden cube stick together. The cube moved at a velocity of 40 cm/s after the impact. Calculate the final velocity of the bullet.
