F The Figure shows an approximate representation of the contact force versus time during the collision of a 46 - g tennis ball with a wall. The initial velocity of the ball is 4.239e+01 m/s perpendicular to the wall. What is the speed of the tennis ball after the collision? 2000 1500 1000 500 2 Time (ms) 6 8 10

Ball B, moving in the positive direction of an x axis at speed v, collides with stationary ball A at the origin. A and B have different masses. After the collision, B moves in the negative direction of the y axis at speed v/3. In what direction does A move, as an angle with respect to the x axis? Number i Units

A block of wood, with mass 1.50 kg, rests stationary on horizontal ground.The coefficient of kinetic friction between the block and the ground is 0.933.A bullet, with mass 0.250 kg, moving horizontally, hits and sticks into the block of wood.We find that the speed of the block of wood, with the bullet embedded in it, just after the collision is 11.5 m/s. a) Calculate the speed of the bullet before hitting the block of wood. m/s(b) Calculate how far the block slides along the ground before coming to rest. Also include a diagram showing physical situation and coordinates
