A crate has a mass of 24 kg. What applied force is required to produce an acceleration of 3 m/s2 if the frictional force is known to be 90 N?

A block weighing 38 kg is on an incline with a slope of 17o. If the block is at the verge of sliding down the incline, what is the static frictional force of resistance? A block weighing 25 kg is on an incline with a slope of 28o. If the block is at the verge of sliding down the incline, what is the static friction coefficient?

A steel beam is suspended from two ropes as it is lifted to the top of a building at a constant speed. One of the ropes makes an angle of 25.2 degrees with respect to the vertical and has a tension of 722 N, while the other makes an angle of 29.5 with respect to the vertical. What is the beam's mass in kg?

What net force is required to make a 15 kg box move at a constant speed of 2.0 m/s.

A commercial airplane is coming in for a landing. Just before it hits the runway it is moving at 76 m/s. The plane has a mass of 20,000 kg. The runway is 1.6km long and, obviously, the airplane needs to be stopped before it reaches the end of the runway. How large is the braking force the airplane needs to stop safely before the end of the runway?

For a short period of time, the frictional driving force acting on the wheels of the 2.3-Mg van is FD = (600+2) N, where t is in seconds.

A horizontal force of 734 N is needed to overcome the force of static friction between a level floor and a 132 kg crate. What is the acceleration of the crate if the 734 N force is maintained after the crate begins to move and the coefficient of kinetic friction is 0.07?

While two forces act on it, a particle is to move at the constant velocity = (3.58 m/s) -(-3.26 m/s). One of the forces is F1 = (1.88 N) + (-5.85 N). What is the other force? Number i + i j Units

Following the collision with a tree, the car rapidly decelerates and comes to a full stop in 0.26 seconds. Given that the passenger in the car has a mass of 70.0 kg and experiences a restraining force from the seat belt amounting to 4038 N, what was the car's initial velocity just before the impact with the tree?

A car (mass = 2,335 kg) is traveling +5.8 m/s when the driver applies the brakes.  The car moves 75.3 m before it comes to a complete stop.  What is the force applied by the breaks (assuming it remains constant). Use g=9.8
