1. The problem statement, all variables and given/known data The acceleration of a particle is 5 m/s^2. What is the acceleration in Km/hr^2 and ft/hr^2? 2. Relevant equations 1km=1000m , 1m = 3.28 ft , 1hr=3600s 3. The attempt at a solution ok so i have answers with calculator which is 5m/s^2 = 64800 km/hr^2 and 212598425 ft/hr^2 I tried doing it by showing the process but i couldnt get the same answer the square parts confuse me when doing the math can anyone plz show me how to do the process of getting those answers thanks. for example : 5 x (1 meter / 1 second ^2 ) 5 x( ? kilometer / ? hour^2) Like that by replacing and doing the math :D .
