(-)11,666.67 N. To calculate this, you need to use the impulse-momentum principle, whereby the change in momentum is equal to the force multiplied by the time over which the force is applied. The change in momentum here is the final speed x the mass - the initial speed x the mass. Then divide the answer by the time (six seconds) and the answer will be the force applied (in this case the answer is negative as the force is applied in the direction opposite to the direction of the truck's motion.)
Its average speed was 1/2 of (30 + 0) = 15 meters per second.Distance = (average speed) x (time) = 15 x 7.2 = 108 meters .

You can't figure "acceleration" from this information. Maybe you meant "Deceleration"? Ask again.

Friction slows down the motion of an object when it is the only force acting on it. It opposes the object's movement, causing it to eventually come to a stop.
Friction is a force that slows down or stops motion by acting opposite to the direction of movement. It arises when two surfaces rub against each other, creating resistance that impedes the motion.
It's a deceleration of 2.93 meters per second squared
Friction is the force that stops or slows down motion by acting in the opposite direction to the direction of the object's motion. It occurs when two surfaces rub against each other, creating resistance that opposes the movement of the object.
The net force acting on the object determines how much it speeds up or slows down. If the force is in the same direction as the object's motion, it speeds up; if it's in the opposite direction, it slows down. The object's mass also plays a role, with more massive objects being harder to speed up or slow down.
If a box is slowing down while being pushed, it suggests that there is an unbalanced force acting on it. The force causing the box to slow down is greater than the force pushing it, creating an imbalance.

As long as the book's velocity changes, there is a net forces acting on it - in other words, the forces are unbalanced. By the way ... How exactly does a book that is resting on a table slow down and come to a stop ?
The upward force in a parachute jump is caused by air resistance or drag acting on the parachute as it opens and expands. This creates a drag force that slows down the descent of the jumper, allowing them to land safely.
Inthe kicking force, kinetic energy is acting on the ball together with Gravitational Potential Energy. Whereas the part where aother force is acting on iit while the ball is not moving is alsoocontrolled by gravitaitional potential energy.
The limiting frictional force is the force that slows down the tennis ball on the roller coaster.
