"hello everyone welcome to little this is
priya
and here we have an exciting question
let us try to solve this question
so the question is a horse continues to
apply a force
in order to move a cart at a constant
speed
explain why so when coming to the
question a horse will
continuously apply a force to move a cut
because in a constant speed why
the horse has to apply force on the car
to
make the car to move at a constant speed
this is because when the car moves on
the road
the road encounters a friction against
this
moving cart so in order to keep the
cart moving horses should overcome the
friction
on which the road is applying on the
cart
so to overcome the friction which has
been
applied on the cart that horse has to
continuously apply some force
this makes the guard to move at a
constant speed
so that's why the horse has to apply
more and more force on the cart
in order to overcome the friction what
has been applied on the
card by the road so that's why the horse
has to apply more and more force
so this is the reason why the horse is
continuously applying a force
on a car to move at a constant speed
