A tennis ball of mass 5.0×10−2 kg and speed 17 m/sm/s strikes a wall at a 45 ∘ angle and rebounds with the same speed at 45 ∘

A projectile of mass m, = 2.00kg is fired at an asteroid of mass M 400kg at a speed of m Vo =1000- S in the direction shown. The asteroid breaks into two pieces, m, =100kg and m m2 300kg. The final speeds of the asteroid pieces are v, =10.00- * and v, = 5.00 in the S S directions shown. What are the final speed and direction of the velocity of the projectile after the collision? (Note: The projectile has not been drawn in the "after" picture of the diagram but must be included.) Before After V715° m, Vo M m. v 35°

Taking the density of air to be 1.29 kg/m^3, what is the magnitude of the linear momentum of a cubic meter of air moving with the following wind speeds? (A) 26 km/h (b) 74 mi/h - the wind speed at which a tropical storm becomes a hurricane

Two objects of masses m1 = 2.0 kg and m2 = 1.3 kg moving towards each other with speeds of 2.2 m/s and 3.1 m/s, respectively, collide inelastically. Calculate the amount of kinetic energy lost in this collision, in joules.
