the velocity of retarding body change from 90 kilometre per hour to 36 km per hour find change in velocity in m per s!

✧This is a combination of two steps!

❥First the change is velocity is the difference between the initial and final velocities. Technically we have to know something about the direction of motion, but if we assume that these are in the same direction the velocity goes from 90 km/hr to 36 km/hr, which is a decrease of 54 km/hr.

❥Second you need to convert the change in velocity that you just calculated and convert the units from km/hr to m/s. Every 1 km is 1000 m and every 1 hr is equal to 3600 s (1 hr is 60 minutes and every minute is 60 seconds).

❥The conversion would be setup as follows

❥Since a change in velocity is really a vector, you would need to specify the direction of the velocity change as opposite the direction of motion!
