A 2.64-kg steel ball strikes a massive wall at 10.0 m/s at an angle of 0- 60.0° with the plane of the wall. It bounces off the wall with the same speed and angle (see the figure below). If the ball is In contact with the wall for 0.164 s, what is the average force exerted by the wall on the ball? magnitude direction --Select-- v

A 3.00-kg steel ball strikes a wall with a speed of 10.0 m/s at an angle of 60.0° with the surface. It bounces off with the same speed and angle.

As it is sliding across ice, an internal explosion breaks an 80 kg object into two pieces. One piece has a mass of 33 kg and moves off with a speed of 15 m/s at an angle of 40° relative to the initial path of the object. If the object was initially moving at 20 m/s. (a) What is the speed and direction of the other piece after the explosion? Be sure to explain how you are able to determine this. (b) Compare the kinetic energy of the single object before the explosion to the total ki- netic energy of the two pieces after the explosion. Explain how this relates to the term 'explosion'.

Cons Block 1, of mass m1 = 2.90 kg , moves along a frictionless air track with speed vị with block 2, of mass m2 = 57.0 kg , which was initially at rest. The blocks stick together after the collision. (Figure 1) 13.0 m/s. It collides %3D Part A Part B Part C What the change AK = Kfinal – Kiniti. in the two-block system's kinetic energy due the collision?

Problem-3: A ball of mass 200 gram strikes a wall perpendicular to its surface at a speed of 10 m/s and rebounds back at the speed of 5 m/s. It is in contact with the wall for 2 milli-sec. Find the average force exerted by the wall on the ball.

A ball has a mass of 10-Kg and is traveling to the right at 30 m/s. A second ball, which is suspended from a string and has a mass of 15-Kg, is traveling to the left at 12 m/s. The two balls experience an elastic head-on collision when the string is vertical. Determine:a) the speed of each ball after impactb) the height that the second ball will rise with respect to its lowest position (AFTER IMPACT)

An isolated system consists of two objects, A and B, moving without friction along a horizontal x-axis. The figure shows the initial masses and speeds of these objects. 7.00 m s-¹ 2.00 kg A Check 5.00 m s-¹ Final kinetic energy initial kinetic energy = || 3.00 kg The two objects then suffer an inelastic collision, after which they remain stuck together, traveling as a single composite object, confined to the x-axis. None of these objects rotates. - B What is the difference between the final kinetic energy of the composite object and the total initial kinetic energy of A and B? Give you answer by entering a number, specified to an appropriate number of significant figures, into the empty box. V J.

QUESTION 8 Two carts of masses m1 and m2 are moving towards each other with speeds v1 and v2. respectively. The carts collide head-on, elastically. For the values listed below, total kineti energy of the two carts after the collision, in joules, is: m1 = 6.00 kg m2 = 3.51 kg 1 = 2.18 m/s 2 = 7.00 m/s
