Which statement about a pair of units is true?
grandymaker [24]

Answer:

option A is correct as 1 yard consist of 0.9144 meter which is less than one meter

Explanation:

from the above given statement option 1 is true

1 yard is equal to 0.9144 meter

while

1 mile is equal to 1.60934 km

1 foot is equal to 30.48 centimeter

1 inch is equal to 2.54 centimeter

therefore all these units [left one] are larger than their respective conversion [ right one unit]

therefore option A is correct as 1 yard consist of 0.9144 meter which is less than one meter

A car is strapped to a rocket (combined mass = 661 kg), and its kinetic energy is 66,120 J.
Katen [24]

Answer:

9.4 m/s

Explanation:

The work-energy theorem states that the work done on an object is equal to the change in kinetic energy of the object.

So we can write:

W=K_f - K_i

where in this problem:

W = -36.733 J is the work performed on the car (negative because its direction is opposite to the motion of the car)

K_i = 66,120 J is the initial kinetic energy of the car

K_f is the final kinetic energy

Solving for Kf,

K_f = W+K_i = -36,733+66,120=29,387 J

The kinetic energy of the car can be also written as

K_f = \frac{1}{2}mv^2

where:

m = 661 kg is the mass of the car

v is its final speed

Solving, we find

v=\sqrt{\frac{2K}{m}}=\sqrt{\frac{2(29,387)}{661}}=9.4 m/s
