Sol:
25) speed is the rate at which position changes, so (c) is correct
(c) The rate at which your position changes.
26) Free fall means when a body fall under the effect of gravity only neglecting any other forces like air resistance, so (c) is correct.
(c) when an object falls solely due to gravity force.
27) if acceleration a= 0 m/s² then velocity is constant and using relation
Velocity = distance/time
For given condition time = 1 sec, velocity= 5m/s
So distance = 5 meters
(c) is correct.

An object is thrown directly downward from the top of a very tall building. The speed of the object just as it is released is 29.3 m/s. After being thrown, the object falls freely due to gravity. Neglect air resistance and calculate the distance, in meters which the object covers between times t1 = 1.77 s and t2 = 5.02 s after it is thrown.

7) A 21-ton (42,000-lb) truck collides with an 2300-lb car and causes a lot of damage to the car. During the collision A) the force on the truck due to the collision is greater than the force on the car, and the truck experiences greater acceleration. B) the force on the truck due to the collision is greater than the force on the car, and the car experiences greater acceleration. C) the forces on the truck and car are equal,...
When an object falls in Earth's gravitational field (think of a skydiver jumping from an airplane or a marble falling in a tank of oil)
When an object falls in Earth's gravitational field (think of a skydiver jumping from an airplane or a marble falling in a tank of oil), it accelerates due to the force of gravity. If gravity were the only force acting on the object, then all objects-elephants and feathers alike would fall at the same rate. But gravity is not the only force present. Moving objects also experience resistance or friction from the surrounding medium; it would be air resistance for...

An object is projected with initial speed v0 from the edge of the roof of a building that has height H. The initial velocity of the object makes an angle α0 with the horizontal. Neglect air resistance. A) If α0 is 90∘, so that the object is thrown straight up (but misses the roof on the way down), what is the speed v of the object just before it strikes the ground? Express your answer in terms of some or...

Show work/formula Like Newton, you will calculate the speed of a projectile to determine how to put an object in orbit. In addition, with your calculations, you will provide a diagram that shows the projectile and how it would move when it becomes a “satellite.” Here is the information you require: The projectile’s mass is not needed. The projectile must be launched on the horizontal plane. The earth drops 8 inches for every mile traveled. The...

A common misconception about Newton’s first law is that when no net force acts on an object, the object must be at rest (i.e. stopped). Here, we will illustrate an example that shows this conception to be false. When a skydiver jumps out of an airplane, she is initially in free-fall and therefore has a downward acceleration of one ‘g’ due to the force of gravity. As she falls, gravity speeds her up. But the faster she goes, the more...

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...
