A student pushes a physics textbook of mass 1.15 kg across a table with a horizontal force of 5.48 Newtons. If the frictional force between the table and the textbook is 3.38 Newtons and the textbook was initially at rest, what is the speed of the textbook after 2.3 seconds? Remember to give your answer in metres per second and to at least 3 significant figures.

An object with a mass of 1.93 kg is initially at rest upon a horizontal, frictionless surface. An applied force of 3.92 Ni acts on the object for 2.13 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 rock of mass m falls from the top of a cliff and it experiences a significant amount of air drag as it falls. The rock has a mass of 3.6 kg and the cliff is 55 m tall. If it is going 22 m/s when it hits the ground, what was the average force of air resistance? Express your answer to two significant figures and include the appropriate units.
A box of mass 19 kilograms is sliding along at 1.4 meters per second. Roy pulls the box in the same direction it's moving with a 52-newton force at an angle of 28 degrees. The coefficient of kinetic friction between the box and the floor is 0.26, and Roy pulls on the box for 15 meters. What is the speed of the box when Roy just finishes pulling?
A horizontal force is applied to an object weighing 392 N that causes its speed to increase uniformly from 0 m/s to 6 m/s in 3 seconds. If we disregard the friction value, calculate the applied force
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 fast is the coyote moving when he has traveled 2.11m while he is slowing down? Assume his initial speed when he is slowing down is equal to his final speed when the rockets were firing.
Your answer is partially correct. A 19-kg sled is being pulled along the horizontal snow-covered ground by a horizontal force of 21 N. Starting from rest, the sled attains a speed of 1.8 m/s in 8.1 m. Find the coefficient of kinetic friction between the runners of the sled and the snow. Number 0.09 Units No units

Read the scenario. A cyclist is riding his bike at a constant speed of 5 m/s, and experiences a frictional force between the bike and sidewalk of 100 N. The cyclist then changes his speed to 10 m/s. What effect does this increase in speed have on the frictional force between the bike and sidewalk? A) The frictional force doubles because when speed increases frictional force also increases. The frictional force doubles because when speed increases frictional force also increases. B) The frictional force becomes half of what it was because when speed increases, frictional force decreases. The frictional force becomes half of what it was because when speed increases, frictional force decreases. C) The frictional force between the bike and sidewalk stays the same because speed does not affect frictional force. The frictional force between the bike and sidewalk stays the same because speed does not affect frictional force. D) The frictional force increases, but does not…
