Answer:
10.53m/s²
Explanation:
Centripetal acceleration is the acceleration of an object about a circle. The formula for calculating centripetal acceleration is expressed by:
v is the velocity of the car = 24.5m/s
r is the radius of the track = 57.0m
Substitute the given values into the formula:
Hence the centripetal acceleration of the race car is 10.53m/s²
Answer: Radio waves and light waves are both electromagnetic raidiations.

Answer:
Gravitational potential energy, kinetic energy and mechanical energy
Explanation:
The body is at a displacement to the gravity and therefore has energy stored in it as a result of its displacement against gravity. When this body is released the gravitational potential energy is converted to translational kinetic energy as well as rotational kinetic energy as it rolls down the the ramp. The sum of the kinetic energies and potential energy of the body amount to the mechanical energy of the ball down the ramp.
Answer:
slightly higher than y
Explanation:
The initial/previous upward component of the bullet's velocity does not really have effect on the constant downward acceleration due to gravity. Since you must aim upward, there will be less or declined horizontal velocity, therefore it will take more time for the bullet to get to the plane of the target or aim. The bullet will now have more time to drop away from the straight line path along which it was aimed.
Furthermore, this problem assumes ideal or perfect conditions (no effects from air resistance). The high speed of a bullet has no much or less effect in this regards.
