Answer:
False
Explanation:
False
If brakes fail then we should not run against any object or wall to slow down the speed instead we should use friction forces slow down the car and shift gear to neutral to cease any acceleration.
By driving zig-zag motion friction force on the tires may stop the car after some distance.
Do not try to shut off the engine as it will lock the steering mechanism any prove fatal.
The force that gravitation exerts upon a body, equal to the mass of the body times the local acceleration of gravity is known as weight.
Weight is the force of gravity acting on a body.
The formula is :
W =mg
Here,
W is the weight or force acting on the body. m is the mass of the body, and g is the gravitational acceleration.
Since weight is also a force, so its SI unit is also newton. The value of weight varies from place to place depending on the gravity. Its value can also be equal to zero.

I'm not sure about the magnitude, but the direction of the normal force is upward.
