The kinetic energy of the car is
Explanation:
The kinetic energy of an object is the energy possessed by the object due to its motion.
Mathematically, the kinetic energy is
where
m is the mass of the object
v is its speed
For the car in this problem,
m = 740 kg
v = 33.5 m/s
Therefore, the kinetic energy of the car is

It is correct, the action is paddling, where you move the water backwards, and the reaction is the boat moving forwards.
Electrical energy is a particle that moves through a wire and transferred into homes, work, etc to make electricity work in objects.
Answer:
Explanation:
Time of flight is the time taken by the bulet in air. Time of flight is expressed as T = Usinθ/g where;
U is the initial velocity = 180m/s
θ is the angle of launch = 90° (Since the bullet is shot upwards)
g is the acceleration due to gravity = 9.81m/s²
T = 180sin90/9.81
T = 180/9.81
T = 18.35s
<em>Hence the bullet will spend 18.35s in air</em>
<em></em>
The height covered by the bullet is the maximum height. Maximum height is expressed as;
H = u²sin²θ/2g
H = 180²sin²90/2(9.81)
H = 180/19.62
H = 9.17m
<em>Hence the bullet will go 9.17m high</em>
I think that peeing might be the correct answer? xD
