You are standing on a sheet of ice that covers the football stadium parking lot in Buffalo; there is negligible friction between your feet and the ice. A friend throws you a 0.375 kg ball that is traveling horizontally at 9.50 m/s . Your mass is 65.0 kg. A. If you catch the ball, with what speed do you and the ball move afterwards? B. If the ball hits you and bounces off your chest, so that afterwards it is moving horizontally at 8.30 m/s in the opposite direction, what is your speed after the collision?
A projectile is fired from point 0 at the edge of a cliff, with initial velocity components of v0x=60 m/s and v0y=175 m/s, What is the magnitude of the velocity of the projectile 21.0s after it is fired
A large mirror is hung from a nail. The supporting steel wire has a diameter of 0.20 mm and an unstretched length of 1.60 m. What is the distance between the nail and the top of the frame
A uniform magnetic field of magnitude 1.00 T is directed perpendicular to the plane of a rectangular loop having dimensions 8.1 cm by 10 cm
Vector A has a magnitude of 116 units and points 37.0 ° north of west. Vector B points 69.0 ° east of north. Vector C points 17.0 ° west of south. These three vectors add to give a resultant vector that is zero. Using components, find the magnitud..
