Two bodies start moving in the same straight line at the same instant of time from the same origin. The first body moves with a constant velocity of 40ms^-1, and the second starts from rest with a constant acceleration of 4ms^-2.Find the time that elapses before the second catches the first body. Find the also the greatest distance between them prior to it and time at which this occurs

Two particles ,
what is the speed of the car? ,
Two particles, 1 and 2 move with constant velocities v 1 and v 2 along two mutually perpendicular straight lines towards the intersection point O. At the moment t=0 the particles were located at the distance l 1 and l 2 from the point O. How soon will the distance between the particles become the smallest? What is it equal to?

From point A located on a highway (shown in figure above) one has to get by car as soon as possible to point B located in the field at a distance l from the highway. It is known that the car moves in the field η times slower than on the highway.

A police jeep, approaching a right-angled intersection from the north, is chasing a speeding car that has turned the corner and is now moving straight east. When the jeep is 0.6 km north of the intersection and the car is 0.8 km to the east, the police determine with radar that the distance between them and the car is increasing at 20 km/h^-1. If the jeep is moving at 60 km h^-1 at the instant of measurement, what is the speed of the car?
