WebThe first answer was correct, displacement does need a quantity and direction. Displacement can be calculated by measuring the final distance away from a point, and then subtracting the initial distance. Displacement is key when determining velocity (which is also a vector). Velocity = displacement/time whereas speed is distance/time. WebYou can, of course, rearrange the equation to solve for either distance or time time = distance v avg. distance = v avg × time Suppose, for example, a car travels 150 kilometers in 3.2 hours. Its average speed for the trip is v avg = distance time = 150 km 3.2 h = 47 km/h.

WebJan 16, 2005 · There is also an angle at the bottom. The first part of the question asks to find the minimum coefficient friction, so that the ladder does not slip, which I found was 0.5*L*m_2*g+m_1*g*d)/ (L*tan (theta)* (m_2*g+m_1*g)) Then, part B of the question is to find the magnitude of the force of friction that the floor applies to the ladder. WebFigure 3.30 (a) Velocity of the motorboat as a function of time. The motorboat decreases its velocity to zero in 6.3 s. At times greater than this, velocity becomes negative—meaning, the boat is reversing direction. (b) Position of the motorboat as a function of time. At t = 6.3 s, the velocity is zero and the boat has stopped. At times ... Webvelocity of AB = 60 rad/s. Notice that rod AB rotates about a fixed point A.
