Answer» Mass m = 7.5 × 10^(-4) KG Time t = 0.5 sec LENGTH l = 0.1 m = 10 cm Explanation: 1 dyne = 1×10^(-5) N 1 dyne = 1×10^(-5) Kgm/sec 1 cm/sec^(2) = 0.01 m/sec^(2) # Force; F = ma > a = F/m > a = [30×10^(-5)] / [40×(0.01)] > a = [30×10^(-5)] / [0.4] > a = 7.5×10^(-4) # Time; v = at > t = v/a > t = (20×0.01) / (40×0.01) > t = 0.5 sec # Length; l = vt > l = (20×0.01) × 0.5 > l = 0.1 m = 10 cm HOPE YOU LIKE MY SIMPLEST WAYExplanation: |
