9. Use dimensional analysis to determine which of the following equations is certainly wrong (show proof)< m 2 = vt F = F = h = 2g (2gh)2 a Where i and h are lengths and F is force with dimension of [mass Length Time?]. The other symbols have their usual meaning. e Example answer: for 2 = v t, its dimensional analysis is Length = (length/time)*(time) → so this is correct. 10. A body with initial velocity 8.0 m/s moves along a straight line with constant acceleration and travels 640. meters in 40.0 seconds. For this 40.0 second interval, find e (a) the average velocity in m/s (b) the final velocity (m/s) (c) the acceleration with correct unite
