Answer:

Explanation:

The electromagnetic force of an electromagnet can be increased by:

1. wrapping the wire around the coil more times; or

2. increasing the current passing through the coil.

A 1500 kg aircraft going 35 m/s collides with a 2000 kg aircraft that is parked and they stick together after the collision and
Elis [28]

The two aircrafts are skidded for 14.9 s.

To find the answer, we need to know about the Newton's equation of motion.

<h3>What is the Newton's equation that relates velocity, distance, acceleration and time?</h3>

As per Newton's equation of motion

  • V²-U²= 2aS
  • V= U+at
  • V= final velocity, U = initial velocity, S = distance, a= acceleration, t= time

<h3>What's the acceleration of the aircrafts that skidded from 35 m/s after the collision for 112.1 m before achieving 15 m/s?</h3>
  • Here, U = 35 m/s, V = 15m/s, S= 112.1 m
  • So, 15²- 35²= 2a×112.1= 224.2a

=> a= -1000/224.2= -4.5 m/s²

<h3>What's the time taken to stop if these aircrafts are de-accelerated by 4.5 m/s² from 35m/s?</h3>
  • Here, U = 35 m/s, V=15 m/s a= -4.5 m/s²
  • 35= 15+(-4.5)t

=> t= 20/4.5 = 4.4 s

Thus, we can conclude that the two aircrafts are skidded for 4.4 s.

2. A train is traveling at 75 km/hour. How far can it travel in 20 hours?
zloy xaker [14]

Answer:

As the speed is constant

Distance = Speed x Time

45min = (45/60)hrs = 0.75hrs

Distance = 75 x 0.75 = 56.25km

A horizontal force of 90.0 N is required to push a 75kg object along a horizontal surface at a constant speed. What is the magni
Varvara68 [4.7K]
If the object is moving at a constant speed, acceleration is 0. So:

F = ma&#10;&#10;F = m\times 0&#10;&#10;F = 0

The resultant force is 0. So the force pushing the object must be equal to the friction force acting, so 

Friction = 90 N
