In a football game a kicker attempts a field goal. The ball remains in contact with the kicker's foot for 0.0593 s, during which time it experiences an acceleration of 445 m/s2. The ball is launched at an angle of 48.2° above the ground. Determine the (a) horizontal and (b) vertical components of the launch velocity.
Two cars of collide in a glancing collision and stick together. Before the colli- sion the first car (mass of 500 kg) is moving with velocity 25 m/s at an angle of 30%u25E6 North of East, Determine the momentum of each car in a suitable Cartesian c..
Two sinusoidal waves, identical except for phase, travel in the same direction along a string, producing the net wave y(x,t)=(6.0 mm)sin(24.0x -2.0 s-1 * t+0.320 rad), with x in meters and t in seconds. What is the wavelength ? of the two waves? W..
