Question

An object expirience a net non zero force . it is posible for the object to travel with a constant speed in a straight line.????

Answer 1

Force = mass × acceleration.

When object experience some net force then object have some acceleration , therefore it can not have constant speed.

hope this will help.

Answer 2

yes , the force on the object is zero because 

F = ma 

and acceleration = change in velocity / change in time 

now in straight line motion if the object have constant speed it have also constant velocity because here displacement is equal to the distance and hence if the velocity is constant it mean there is not any change in it so the acceleration become zero

 due to all this the force on the object is also zero
