Answer to Question #244570 in Physics for saud

Question

A body is moving along a straight line with a constant velocity of 64 km/h in the positive sense.

At t = 0 the position of the body was +1.4 km. Find the position of the body at t = 0.25

Answer 1

Given:

$v=64\rm \: km/h$

$x_0=1.4\:\rm km$

$t=0.25\:\rm h$

The final position of the body

$$x=x_0+vt=1.4+64*0.25=17.4\:\rm km$$
