Calculating Original Speed of Truck Travelling 41.7m in 6.2s

[killer22]

if a truck covers 41.7 meters in 6.2 seconds awhile slowing down slowly to final speed of 3.5 m/s.whats its oringal speed?

Please show what you've tried. The problem is very basic kinematics, you should refer to your book, I'm sure it has thorough explanations.

To calculate the original speed of the truck, we can use the formula: speed = distance/time. In this case, the distance covered is 41.7 meters and the time taken is 6.2 seconds. Therefore, the original speed of the truck would be 41.7m/6.2s = 6.74 m/s. This means that the truck was originally travelling at a speed of 6.74 meters per second before slowing down to its final speed of 3.5 m/s. It is important to note that this calculation assumes that the truck was travelling at a constant speed and did not accelerate or decelerate during the 6.2 seconds.
