If A-12.0 İ-36.0 jand B-4.00 i + 10.01, what is the magnitude and direction of C 2B? A + Vector A is 12 units long at an angle of 53 degrees, and vector B is 15 units long at an angle of 45 degrees. Compute C"A B. reporting both the magnitude and the direction of the resultant vector.
025 (part 1 of 4) 10.0 points A man pushes a 24 kg box across a frictionless floor. The box is initially at rest. He initially pushes on the box gently, but gradually in- creases his force so that the force he exerts on the box varies in time as F (7.7 N/s) t. Af- ter 4 s, he stops pushing the box. The force is always exerted in the same direction. What is the velocity of the box after...
