A force of 1.50 N acts on a 0.20-kg cart so as to accelerate it along an air track. The track and force are horizontal and in line. How fast is the cart going after acceleration from rest through 30 cm, if friction is negligible? A 0.50-kg block slides across a tabletop with an initial velocity of 20 cm/s and comes to rest in a distance of 70 cm. Find the average friction force that retarded its motion.

A 80.0 kg skater with the Birmingham Bulls hockey team with an initial speed of 7.8 m/s stops propelling himself and begins to coast across the ice, eventually coming to rest. The coefficient of kinetic friction between the ice and the skate blades is 0.100, and air resistance can be neglected. How far will the skater travel before coming to rest?
A clever coyote uses rocket powered skates to try to catch a roadrunner. The mass of the coyote is 38.1 kg. If the coyote starts from rest, and accelerates to a final speed of 26 m/s in a distance of 2.4 m, how much thrust force did the rockets excert to get him to his final speed? Assume this thrust is constant over the 2.4 m.

An object with a mass of 1.74 kg is initially at rest upon a horizontal, frictionless surface. An applied force of 4.11 N i acts on the object for 2.64 s. What is the object's final speed? Enter a number rounded to 2 decimal places and assume the answer has proper SI Units.
A worker pushes a 35.0-kg package on a horizontal roller-belt conveyor until it reaches a certain speed. The package then coasts on the horizontal conveyor, all the while slowing down, until it comes to a complete stop after moving 1.20 m. While the package is coasting on the conveyor, the opposing friction force averages 6.00 N. Use the WET to find the speed of the package after the worker pushes it and just as it begins to coast. 0.625 m/s 0.759 m/s 0.600 m/s 0.510 m/s 0.802 m/s 0.641 m/s
