How to calculate speed from a graph
WebThe mechanical energy of the object is conserved, E= K+ U, E = K + U, and the potential energy, with respect to zero at ground level, is U (y) = mgy, U ( y) = m g y, which is a straight line through the origin with slope mg m g. … Web12 sep. 2024 · We can solve this problem by identifying Δ v and Δ t from the given information, and then calculating the average acceleration directly from the equation a ¯ = Δ v Δ t = v f − v 0 t f − t 0. Solution First, identify the knowns: v 0 = 0, v f = −15.0 m/s (the negative sign indicates direction toward the west), Δ t = 1.80 s.
