An airplane is in level flight at a velocity of 300 miles per hour and an altitude of 5000ft when I drops a bomb. (a) how long does the bomb take to reach the ground? (b) what will the bomb's velocity be on impact?

25 workers are at a house project that makes them a month to finish in a flash what could possibly be the power of the workers if each worker works for 200N and then man power is increased by 60% to make the work efficient and effective at the same time, and the distance between the project site and the agency is 30 km from each other.

A ball is at rest from the field and some people are running towards it and the ball has a mass of 12 kgs and is in a lift with 3m above the ground , what could possibly the energy o f it if it rolls 8m/s and the second person speeds tha ball by 80 percent and the third person decelerates the ball by 80 percent ending the ball travel at 1500 meters across the field

Wil-E-Coyote drops a bowling ball off a cliff to try to catch the Roadrunner. The cliff is 132m high.

a. How long does it take the ball to fall to the ground?

b. What is its impact velocity?

c. How far does it fall in the first 3.0 seconds?

d. How fast is it going at the end of 3.0 seconds?

e. How long would it take the same ball to fall if the cliff was on the moon (g = 1.63 m/s2

)?

The applied field is further increased till superconductivity is completely destroyed. The strength of the field is now 8/π×10^5gauss. The correlation length of the superconductor is:
