An airliner of mass 1.70 * 105 kg lands at a speed of 75.0 m>s. As it travels along the runway, the combined effects of air resistance, friction from the tires, and reverse thrust from the engines produce a constant force of 2.90 * 105 N opposite to the airliner’s motion. What distance along the runway does the airliner travel before coming to a halt?

A woman pulls a cloth out from under a 200 g bowl sitting on a table. The bowl is 30.0 cm from the far edge of the cloth, and the cloth exerts a friction force of 0.125 N on the bowl. Assume the cloth is pulled with a constant horizontal acceleration of 2.80 m/s2. What distance (in m) does the bowl travel relative to the top of the table? (Assume the cloth moves in the +x-direction and notice that it moves more than 30.0 cm relative to the top of the table.)

A 3 kg particle moves along an x axis, being propelled by a variable force directed along that axis. Its position is given by x = 2 m + (2 m/s)t + ct2 - (3 m/s³)t³ with x in meters and t in seconds.The factor c is a constant. At t = 4 s the force on the particle has a magnitude of 33N and is in the negative direction of the axis. What is c? Number Units

Suppose that Zak's younger cousin, Greta, sees him sliding across the hall and takes off her shoes so that she can slide as well (assume her socks have the coefficient of kinetic friction of 0.250). Instead of getting a running start, she asks Zak to give her a push. So, Zak pushes her with a force of 125 N over a distance of 1.00 m. If her mass is 20.0 kg, what distance d does she slide after Zak's push ends? Remember that the frictional force acts on Greta during Zak's push and while she is sliding after the push.

Two crates of fruit  are released from the top of a ramp inclined at 30 degrees from the horizontal and 4.5 meter long. The two crates consist of  an apple crate of mass 20 kg that is placed in front of a watermelon crate of mass 80 kg.  The apple crate has a coefficient of friction of 0.20 while the watermelon crate has a coefficient of friction of 0.15. How long does it take the apple crate to reach the bottom of the incline if it needs to travel a distance of 4.5 meters?

A 63.0-kg box is pulled by a rope making an angle of  θ = 22.0°  with the horizontal. The tension in the rope is  34.5 N.  (Assume the surface the box slides across is frictionless.)If the box starts from rest, determine the time required to move the box a horizontal distance of 2.67 m.

A parachutist whose mass is 75 kg drops from a helicopter hovering 2500 m above the ground and falls toward the ground under the influence of gravity. Assume that the force due to air resistance is proportional to the velocity of the parachutist, with the proportionality constant b₁ = 20 N-sec/m when the chute is closed and b₂ = 100 N-sec/m when the chute is open. If the chute does not open until the velocity of the parachutist reaches 30 m/sec, after how many seconds will the parachutist reach the ground? Assume that the acceleration due to gravity is 9.81 m/sec². The parachutist will reach the ground after (Round to two decimal places as needed.) seconds.
