Question

A small object P moves along a straight path. The position coordinate of P is known to be x = (t^2 - 2t + 10) meters, where t is time in seconds. The total distance traveled by P in 10s is? 082 m 80 m 90 m 100 m

Answer 1

Option C : 90 m

Given Data

Position Cordinate of P is given by

I= t - 2t + 10

Where 't' is time in sec.

To Find

Distance Travel by P in 10 seconds

Solution

I= t - 2t + 10

Putting t=10

I = 102 – 2 * 10 + 10

I = 100 – 20 + 10

06 = 1

Hence Distance traveled by P in 10 seconds is 90 m.

Option C is Correct Answer
