A drag racer, starting from rest, speeds up for 404 m with an acceleration of +18.4 m/s2. A parachute then opens, slowing the car down with an acceleration of -5.92 m/s2. How fast is the racer moving 3.28E+2 m after the parachute opens?

Three students converge on the last textbook in the store. All three grab it and begin to pull in the directions shown in the above figure. Student A exerts a force of 58.56 N, student B pulls with a force of 37.76 N, and student C pulls with a force of 124.91 N at an angle θ(theta)=81.6 degrees...

A Boeing 747 "Jumbo Jet" has a length of 59.3 m. The runway on which the plane lands intersects another runway. The width of the intersection is 23.3 m. The plane decelerates through the intersection at a rate of 5.51 m/s2 and clears it with a final speed of 46.6 m/s. How much time is needed for...

A bullet is fired through a wooden board with a thickness of 10.0 cm. The bullet hits the board perpendicular to it, and with a speed of +430 m/s. The bullet then emerges on the other side of the board with a speed of +344 m/s. Assuming constant acceleration (rather, deceleration!) of the bullet...
