The block stays in one piece , the initial kinetic energy of the block is 3.96547 x 10⁶ gm²/sec.

<h3>What is kinetic energy?</h3>

Kinetic energy is defined as the energy that a moving thing possesses. The effort needed to move a mass-determined body from rest to the stated velocity is how it is defined. Until its speed changes, the body maintains the kinetic energy it gained during its acceleration.

Kinetic energy can be expressed as

KE = 1/2 mv²

Given m = 10.9 g

V = 853 m/s

KE = 1/2 x 10.9 g x 853 m/s

KE = 1/2 x 10.9 x 727609

KE = 3.96547 x 10⁶

Thus, the block stays in one piece , the initial kinetic energy of the block is 3.96547 x 10⁶ gm²/sec.

It takes about 20 seconds for a jet plane to go from rest to the takeoff speed of 100 mph (44.7 m/s). What is the average horizo
Ksju [112]

Answer:

Correct answer:  F = 214.56 N

Explanation:

Given:

V₀ = 0 m/s   initial speed

V = 44.7 m/s  speed after t = 29 seconds

m = 96 kg

F = ?  horizontal force

Taking off an airplane is a uniformly accelerated motion to which the formula applies:

V = V₀ + a t   and  V₀ = 0 m/s

V = a t  ⇒ a = V / t = 44.7 / 20 = 2.235 m/s²

a = 2.235 m/s²

the horizontal force is calculated using the formula:

F = m · a = 96 · 2.235 = 214.56 N

F = 214.56 N

18. Compared to its weight on Earth, a 5 kg object on the moon will weigh A. the same amount. B. less. C. more.
s2008m [1.1K]

Answer:

B. less

Explanation:

acceleration due to gravity on Earth, g = 9.8 m/s²

acceleration due to gravity on Moon, g = 1.6 m/s²

Given mass of the object as, m = 5 kg

Weight of an object is given as, W = mg

                                                         

Weight of the object on Earth, W = 5 x 9.8 = 49 N

Weight of the object on Moon, W = 5 x 1.6 = 8 N

Therefore, the object weighs less on the moon compared to its weight on Earth.

The correct option is "B. less"
