It will depend on the frictional force involved in the two. I think it will take more force in sled.
The average speed is 42.7 m/s
Explanation:
The speed of an object in uniform motion (=moving at constant speed) is given by the equation:
where
v is the speed
d is the distance
t is the time
For the car in this problem, we have:
d = 2560 m (distance)
t = 60 s (time)
Solving the equation, we find the average speed:

Answer:
0.001067 Wb
Explanation:
Parameters given:
Magnetic field, B = 0.77 T
Angle, θ = 30º
Width = 0.4cm = 0.04m
Length = 0.4cm = 0.04m
Magnetic flux, Φ(B) is given as:
Φ(B) = B * A * cosθ
Where A is Area
Area = length * width = 0.04 * 0.04 = 0.0016 m²
Φ(B) = 0.77 * 0.0016 * cos30
Φ(B) = 0.00167 Wb
Train has the most momentum if they were all traveling 50 mph
<u>Explanation:</u>
- A train can have the most momentum even if it is moving slowly because it has a large mass if they were all traveling 50 mph.
- In simple words, momentum can be described as the amount of motion of a moving body, estimated as a product of its mass and velocity.
- <u>Momentum= mass x velocity</u>
