Chapter 6Circular Motion and Other Applications of Newton's Laws
1. A race car travels 40 m/s around a banked (45 with the horizontal) circular (radius = 0.20 km) track.
What is the magnitude of the resultant force on the 80-kg driver of t
Chapter 2Motion in One Dimension
1. The position of a particle moving along the x axis is given by x = (21 + 22t 6.0t2)m, where t is in s.
What is the average velocity during the time interval t = 1.0 s to t = 3.0 s?
a. 6.0 m/s
b. 4.0 m/s
Chapter 9Linear Momentum and Collisions
1. A 2 000-kg truck traveling at a speed of 6.0 m/s makes a 90 turn in a time of 4.0 s and emerges from
this turn with a speed of 4.0 m/s. What is the magnitude of the average resultant force on the
Chapter 12Static Equilibrium and Elasticity
1. A uniform ladder 15 ft long is leaning against a frictionless wall at an angle of 53 above the
horizontal. The weight of the ladder is 30 pounds. A 75-lb boy climbs 6.0-ft up the ladder. What
Chapter 5The Laws of Motion
1. In the figure, if the tension in string 1 is 34 N and the tension in string 2 is 24 N, what is the mass of
the object shown?
Chapter 8Conservation of Energy
1. A single conservative force Fx = (6.0x 12) N (x is in m) acts on a particle moving along the x axis.
The potential energy associated with this force is assigned a value of +20 J at x = 0. What is the

In this lab, we have two parts: standard deviation and normal distribution. In the first part, we
will show that double the time of measurements wont half the percentage of errors by comparing
Torque Theorem Lab
Group Lab Report
The torque theorem is used in daily life as an example of how much force is exerted on
rotating objects. We can use this theorem to find the acceleration of pulleys, disks, and many
other objects that h
Newtons First Law Lab - Group Report
1. Weights : 500g x 2, 200g x 3, 100g x 1, 50g x1
3. Metal plate with holes on the edge
4. Pulley gear
6. Meter stick
In this lab, we will show that an object under the influence of gravity alone accelerates at a
constant rate. We will also compare the experiment result with the actual gravity acceleration in
