A banked curve is designed for a roadway. The curve is designed so that a car traveling at 19.2 m/s can negotiate it without rel

ying on the force of static friction. The radius of the curve is 51.2 in and the car has a mass of 2300 kg. a. What angle is the curve banked at (degrees)? b. What is the magnitude of the Normal force (N) between the road and the car when it is traveling at the designed speed? c. If a careless driver tries to negotiate the curve at a speed of 25 m/s ,will the direction of the frictional force be inward or outward?

If a boy (m = 25 kg) at rest on skates is pushed by another boy who exerts a force of 500 N on him and if the first boy's final
Bond [772]

Answer:

1 second

Explanation:

The impulse exerted on the boy is equal to its change of momentum:

I = \Delta p\\F \Delta t = m \Delta v

where

F = 500 N is the push on the boy

\Delta t is the contact time

m = 25 kg is the mass of the boy

\Delta v = 20 m/s is the change in velocity of the boy

Solving the formula for the contact time, we find

\Delta t=\frac{m\Delta v}{F}=\frac{(25 kg)(20 m/s)}{500 N}=1 s

In which direction does the sun appear to move across the sky?
sergiy2304 [10]

Answer:

If we consider a system where the y-axis as the South-North line, and the x-axis as the West-East line (where North and East are the positive sides)

We know that the sun goes from East to West, so in our system, the sun goes from the positive side of the x-axis to the negative side of the x-axis.

Where we would see this if we were standing right in the equator line.

If we where in other point of the planet, the Sun will stil move from East to West, but it will have a little tilt along the path, so we will have a little displacement in the y-axis. This displacement will depend on where we are, if we are at the North of the equator, we will se that the sun seems to go a little towards South as it goes to the West side.
