2000-kg car traveling at 23 m/s takes 54 m to stop under full braking.  The same car under similar similar road conditions, traveling at 35 m/s takes _________ m to stop under full braking.

A plane has a mass of M = 201 tons takes-off at a speed of Vf = 243 km/hr. If it starts form rest, what should be the minimum acceleration to take off if the length of the runway is L = 1.7 km

You place a crate of mass 26.3 kg on a frictionless 4.29-meter-long incline. You release the crate from rest, and it begins to slide down, eventually reaching the bottom 1.66 s after you released it. What is the angle of the incline?     18.5 degrees     22.2 degrees     26.6 degrees     20.4 degrees

A loaded sledge of overall mass 90 kg, starting from rest,  slides down a smooth incline of 1 in 10 and takes 10 seconds to reach the bottom of the slope. The speed at the end of the ride and the distance of travel are:

You place a crate of mass 29.8 kg on a frictionless 3.39-meter-long incline. You release the crate from rest, and it begins to slide down, eventually reaching the bottom 1.48 s after you released it. What is the angle of the incline?     21.2 degrees     18.4 degrees     23.9 degrees     28.7 degrees

Construction workers are building a new skyscraper in a major city. A crane operator is using a crane to lift a heavy box of supplies (with a mass of 664 kg) to the top of the building when the cord suddenly snaps! The box of supplies free-falls to the ground from a height of 142 m.  How many seconds does it take for the supplies to crash into the ground below? _____s

A 20 kg crate accelerates along a horizontal floor when it is pushed with a resultant force of 10 N parallel to the floor. How far will the crate move in 5s (starting from rest)?

A magician pulls a tablecloth from under a 200 g mug located 15.0 cm from the edge of the cloth. The cloth exerts a friction force of 0.100 N on the mug and is pulled with a constant acceleration of 3.00 m/s2. How far does the mug move relative to the horizontal tabletop before the cloth is completely out from under it? Note that the cloth must move more than 15 cm relative to the tabletop during the process.

A box is travelling inside an elevator travelling at uniform acceleration and 5 m/s when the box falls out of the elevator. It takes 1.2 seconds to hit bottom of elevator shaft.  a) How long would it take before the elevator reached maximum height? b) How far did the box fall? c) How far did the box fall in 0.2 seconds?
