A body moving with uniform acceleration has initial velocity 45 kilometre per hour and acceleration 20 cm per second square find its velocity after 25 seconds |
|
Answer» Answer: 63km/hr Explanation: GIVEN the INITIAL velocity u=45km/hr=45×5/18m/s given ACCELERATION a=20cm/s²=0.2m/s² since v=u+at=12.5+(0.2)(25) THEREFORE v=12.5+5 v=17.5m/s or 63km/hr |
