Gravity accelerates objects downward at the same rate regardless of the objects mass or falling distance. 1) Does increasing the angle of incline significantly affect the acceleration of the ball? 2) If so, how?
Unless otherwise stated, all objects are located near the Earth's surface, where g = 9.80 m/s2 . A 2600 kg truck tows a 1200 kg car by a chain. f the net forward force on the truck by the ground is 3200 N , what is the acceleration of the car? What is the tension in the connecting chain?
29.) Unless otherwise stated, all objects are located near the Earth's surface, where g = 9.80 m/s2 . An Atwood machine (see the figure (Figure 1)) has suspended masses of 0.28 kg and 0.14 kg . Under ideal conditions, what will be the magnitude of the acceleration of the smaller mass? Express your answer using two significant figures.
Based on what you know about falling objects, select all of the correct statements from the following list. (Ignore the effects of air resistance.) a. The speed of a falling object depends on its weight. b. Objects tend to slow down naturally unless propelled by a force. c. According to tradition, Galileo dropped objects of different mass from the leaning tower of Pisa. d. Inertia is an object's tendency to resist changes in its motion. e. The speed of falling...
Unless otherwise stated, all objects are located near the
Earth's surface, where g = 9.80 m/s^2 .
In the apparatus shown in the figure (Figure 1) , m1 = 15kg
and the coefficients of static and kinetic friction between
m1 and the table are 0.65 and 0.36, respectively.

Unless otherwise stated, all objects are located near the Earth's surface, where g = 9.80 m/s2 . In an emergency stop to avoid an accident, a shoulder-strap seatbelt holds a 62 kg passenger in place. If the car was initially traveling at 86 km/h and came to a stop in 5.6 s along a straight, level road, what was the magnitude of the average force applied to the passenger by the seatbelt?

Common constants: 9.81 m/s2 = gravity on Earth's surface 343 m/s = speed of sound (air @ 20°C) 1440 m/s = speed of sound (water @ 20°C) 1.21 kg/mp = air density (20°C, 1 atm) 998 kg/m3 = water density (20°C, 1 atm) 1 atm = 1.01 x 105 Pa 3 x 108 m/s = c = speed of light (vacuum) 1.661x10-27 kg = p = atomic mass unit Specific Heats: 2040 J/(kg °C) Cwater =...
