A 20.0 kg red curling rock travelling at 0.578 m/s [W] strikes a stationary 20.0 kg yellow curling rock head-on. The collision takes 4.35 ´ 10-2 s. Immediately after the collision, the yellow rock has a velocity of 0.3365 m/s [54.4° N of W]. Using the information from the above narrative, the direction of the red rock immediately after the collision is

A student is driving a 1200 kg car at 42.0 m/s. He is tail-gating ("drafting") behind a 2500 kg truck that is going 40.0 m/s in the same direction as the car. (DON'T EVER DO THIS! IT IS EXTREMELY DANGEROUS AND ILLEGAL) The car collides with the truck and the two vehicles are stuck together. How fast are they moving after the collision?

At the local radio controlled (RC) airfield, a 2.4 kg RC plane strikes a 1.2 kg aerial drone that is hovering stationary at an altitude of 9.6 m.  Just after the collision, the two aircraft are stuck together and moving to the east at 9 m/s at an altitude of 9.6 m. What is the speed (in m/s) of the plane just prior to the collision?

In walking the body goes through both a breaking impulse and a propulsion impulse. The breaking phase lasts .3 seconds and the propulsion phase lasts .33 seconds. The body goes through a decrease of the vertical velocity of .1 m/s as they come into the ground during the breaking impulse and an increase in the vertical velocity of .4 m/s during the propulsion.  The individual has a weight of 700 newtons. What is the acceleration horizontally for both the breaking impulse and the propulsive impulse if the coefficient of friction is .32?

Two billiard balls of mass m (gr) collide with their oblique center. a) Find the post-collision velocity of the balls. b) Find the energy loss that will occur during the collision. m=170 kg   V1= 3.3 m/s   V2=2.8 m/s  Ɵ 1=40   Ɵ 2=38  e=0.5

Need help checking a practice problem. Thanks!

Two automobiles collide. One automobile of mass 1.13 x 103 kg is initially traveling at 25.7 m/s [E]. The other automobile of mass 1.25 x 103 kg has an initial velocity of 13.8 m/s [W]. The vehicles become attached during the collision. What is their common velocity immediately after the collision?

Riding in some bumper cars, you (174 kg for you and car) moving to the right at 15.6 m/s and collide with your younger cousin (145 kg for cousin and car) who is moving to the left at 20.6 m/s. After the collision, you are moving at 9 m/s to the LEFT. What is the velocity of your cousin immediately after the collision?(a) 1.88 m/s to the RIGHT(b) 50.1 m/s to the LEFT(c) 8.92 m/s to the RIGHT(d) 50.1 m/s to the RIGHT(e) 7.43 m/s to the RIGHT

10. The drawing shows a collision between two small balls. Ball (1) has a mass of 135 g and is moving along the x-axis with a velocity of 5.40 m/s. It makes a collision with ball (2), which has a mass of 202 g and is initially at rest. After the collision, the two balls fly apart with angles as shown in the figure below (a the velocity of ball (2) after the collision? m/s 46° and ß = 58°). * m₁ m₂ a +X sf60 sf60 ss/60 ssf6 ssf60 ssf60 ssf60 sehat is the magnitude of O ssf ss500 ssf60 ssf60 ssf60 ssf60 ssf60 s sf60 ssf60 ssf60 ssf60 ssf60 50 ssf60 ssf f60 ssf60 ssf60 ssf60 ssf6 Cost ssf60 ssf60 ssfors f60 ssfoo 60 ssf60 ssf60 s16050 ssf sfoo ssf60 so
