The resultant of the acceleration can be found using:
a = √(ax² + ay²)
a = √(1.5² + 3.7²)
a = 3.99 m/s²
v = u + at, u = 0
v = 3.99 x 6.4
v = 25.5 m/s
Answer:
The one at the front is the driver. he one at the back is the brakeman.
Explanation:
In either a two or a four person bobsled team, the one at the front of the sled is called driver. The one at the back is called the brakeman, and is the one that pushes the back of the sled. The brakeman is the one that jumps in last as the sled gains speed.
In case of the four person, the other two team participants are just referred as riders.
Answer: A) True, you are correct
==================================================
Explanation:
Power in physics is defined as
power = (change in work)/(change in time)
which shows that power is basically the rate of work done. We can think of it like a speed of sorts.
------------
For example, if you apply 100 joules of work over 2 seconds, then,
power = (100 joules)/(2 seconds)
power = (100/2) joules per second
power = 50 watts
A watt is defined to be a joule per second, and it's often used to measure how much electricity is consumed, but it has broader uses in physics as well.
