Question

The velocity and acceleration of a body are 90km/hr and 2m/s^2 respectively. find the distance travelled by it in half minute.

​

Answer 1

1,650 meters

Step-by-step explanation:

Start by converting the velocity to m/s. There are 3600 seconds in a minute and 1000 meters in a kilometer, so 90km/hr=25m/s. Half a minute is 30 seconds, so:

`d=v_ot+(1)/(2)at^2 \\\\d=(25)(30)+(1)/(2)(2)(30)^2 \\\\d=750+900=1650m`

Hope this helps!
