(-)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.)

A car slows down uniformly from 30.0 meter per seconds to rest in 7.20 seconds how far did it travel while decelerating?
Its average speed was 1/2 of (30 + 0) = 15 meters per second.Distance = (average speed) x (time) = 15 x 7.2 = 108 meters .
What force slows a marble rolling on a flat surface?
Gravity!
A skydiver slows down from 65 ms to 5 ms by opening the parachute If this takes 0.75 seconds what is the skydivers acceleration?
80 m/s2 up
A car slows to a stop in 5 seconds if it was going 80 kilometers an hour what was its acceleration?
You can't figure "acceleration" from this information. Maybe you meant "Deceleration"? Ask again.

What is the car's average acceleration if it slows down from 22.0 meter per second to 15.7 meter per second in 2.15 seconds?
It's a deceleration of 2.93 meters per second squared
What effect does friction have on the speed of a moving object?
It slows down or stops the object because of the acting force, pulling it back. Thanks, GeekyScienceGirl123 :]
How to know whether the velocity of a particle increases or decreases?
by analysing the direction of the forces acting on it. If the net force is acting in the opposite direction to the motion, it slows down, if it's in the same direction, it speeds up. If the net force is zero, the object continues moving at a constant velocity
What force slows down the tennis ball on a roller coaster?
The limiting frictional force is the force that slows down the tennis ball on the roller coaster.
What is a slow acting virus?

Air slows the motion of an object by a force called what?
Air resistance.
What force slows and stops?
friction
A force that slows you down?
friction
What kind of friction does a ball meet when it is thrown?
When a ball is thrown into the air, it encounters drag. Drag is the opposing force acting in the opposite direction of the ball. Drag slows down the ball's speed.
Is friction a force that reducues or slows?
reduces
What force slows a skateboarder down?
Friction
Force between two surfaces that slows or stops motion?
Friction is that force.
