Railroad car with a mass of 2000kg is rolling at a speed of 15ms What force would be required to stop the car in 10 second?

mass of the railroad car =2000kg
velocity=15m/s
time=10s
:.Force applied to stop the railroad car=mass X acceleration
=mass X velocity/time
=2000 X 15 / 10
=30000 N
So, the force applied is 30000 N.

0.5 meters per second squared.
What is the weight of a 2000kg elephant in newtons?
In physics mass (M) is a measure of the quantity of matter in a given object. The weight is a force (F) due to gravity. F is derived by multiplying M by acceleration (a). In SI unit M is in kilograms (kg), a in meters per second per second, and F in Newtons. If the elephant has a Mass of 2000kg, its weight on Earth is 2000kg *9. 8 m/s^2 which equals 19,600 N. Its weight on the moon is only 3,246 newtons, because the moon's mass, and the acceleration of gravity there, are smaller than Earth's.

What is the probability of rolling a 6 the first time and a 1 the second time
In rolling a die what is the probability of obtaining a 5 on the first roll and a 6 on the second roll?
1/6 on the first roll, and 1/6 of rolling a six on the second roll. Overall, the chances of you rolling a 5 on the first and a six on the second is 1/3.

When rolling a six on the first roll of a 1 6 number cube and rolling an odd number on the second roll of the same cube?
and the question is ... ?
What is the probability of rolling a 2 and then a 3 with 6-sised cubes?
The probability of rolling a 2 on the first roll is 1 in 6. The probability of rolling a 3 on the second roll is 1 in 6. However, the probability of rolling a 2 on the first roll and 3 on the second roll before you roll at all is 1/6 x 1/6 = 1 in 36.
