You step on the brakes and slow the car to half speed If you release your foot will the car speed up or continue at half speed or slow down?

The car will continue at half-speed.
While you held the brake, the brake pads absorbed kinetic energy from the car's motion. The kinetic energy turned to heat, which, hopefully, was carried away in the air stream through the wheels. (If it doesn't blow away, then your brakes overheat.)
This was energy that was extracted from the gasoline you paid for. It blew away, and your car now has less kinetic energy ... i.e. less speed. If you want more speed again, you'll have to buy and burn more gas.
Here's an exception I can think of ... a case where the car might speed up to its original speed when the brake is released:
If you have the cruise control ON, it's supposed to drop out when you touch the brake. If the cruise is broke and it fails to cut out as it should, then when you release the brake, the cruise would try to take you back up to the speed it's set for.
This would be a dangerous situation.

Suppose that you are in a moving car and the motor stops. You step on the brakes and slow the car to half speed. If you release your foot will the car speed up or continue at half speed or slow down?
Assuming you are not pressing down on the gas, when you release the pedal, the car will slow down over time and evetualy come to a stop. Unless you are going down a hill, in which case you will speed up.
Can speed affect friction force?
Actually, friction does depend on velocity. If you stop your car you have to ease up on the brakes as you slow down because friction increases as you slow down. This effect has been observed for objects travelling at bullet velocities. Friction decrease as speed increases.
Why do objects in space continue to move in a straight line at a constant speed?
Because there is no air in space, there is no friction to slow said object down.
How does an aircraft brake?
When flying, by turning the power to the engines down, or pulling back on the stick. Pulling back on the stick causes the plane to gain altitude at the cost of speed. Turning the power down allows the plane to slow down due to drag. When landing, by using air brakes, by using reverse power (thrust reversers) on the engines, by using car-style brakes on the wheels.
When a car suddenly stops the objects in the back seat are thrown forward. this is due to?
Isaac Newton's first law of motion says that any object which is moving will continue moving in the same direction and speed unless acted on by an outside force. This property of matter is sometimes called "inertia". When your car is in motion, all the things in it are also in motion. When you hit the brakes, the brakes become the "outside force" that slows the car down, but the stuff inside your car has only a fairly minor force - the friction of the object and the seat of the car - to slow it down. So the object tends to continue to move in the same direction until it hits something, such as the back of the front seat.

What happens to the speed of a motor car when brakes are gently applied?
The speed of the motor vehicle is gently slowed down. The more aggressive the brakes are applied the faster the vehicle slows down eventually coming to a full stop.
What are devices used to control the speed and slow down a ship?
Gas pedal and brakes
Do ships have brakes?
They are not brakes like what are in a car, but they do have ways to slow down or stop. In larger ships, reverse thrust is a more common way to decrease speed when underway.
How does brakes and steering of a bicycle help with speed?
When going down a hill, you will pick up much more speed than if on flat roads. If you don't have brakes, you have very little chance of slowing down if something/someone goes infront of your path. The handlebars of a bike don't really affect the speed of the bike, that is more to do with navigation.
When braking a vehicle equipped with anti-lock brakes the driver needs to?
press down hard on the brake pedal, and continue to steer the vehicle.
When putting on the brakes to slow down from a high speed the car shakes what can cause this problem?
Warped brake rotors/drums.
Does a c-130 have speedbrakes?
The C-130 does not have a speed brake. They use a combination of brakes, flaps, and reverse thrust to slow down.
Are ski brakes neccasary?
YES if you don't have brakes if you fall (don't deny it, we all fall no matter how good we are) and your skis release you'll be bootskiing all the way down, not to mention most ski resorts will kick you out if you don't have brakes. It is very important you have brakes.
How do you make a car move by itself?
Start the motor and then put it in gear. Point it down hill and release the brakes
What happens when sudden brakes are applied to the vehicle without using clutch?
If the vehicle is stopped without using the clutch , the engine will give jerks and turn off if the vehicle is in higher gear and the speed is not according to the range of the gear. Although, if the vehicle is being driven in higher gears and slight brakes are applied, no effect will be there if the vehicle's speed remains in the corresponding range. Example: if you are driving a vehicle at 90km/h in 5th gear and you bring it down to 60km/h by applying brakes without using the clutch, nothing will happen and you can continue driving by accelerating again.
