If the speed of a car is increased by 80%, by what factor will its minimum braking distance be increased, assuming all else is t
Vikki [24]

Answer:

KE_2=3.24 \times KE_1

Explanation:

given,

Speed of car = v

new speed of car v'= 1.8 v

Kinetic energy of the car

KE_1 =\dfrac{1}{2}mv^2

new Kinetic energy of energy

KE_2 =\dfrac{1}{2}mv'^2

KE_2=\dfrac{1}{2}m(1.8v)^2

KE_2=3.24 \times \dfrac{1}{2}mv^2

KE_2=3.24 \times KE_1

hence, the kinetic energy is increased by the factor of 3.24.

A speed boat travels from the dock to the first buoy a distance of 20 meters in 18 seconds it began the trip at a speed of 0 m/s
Lunna [17]

Answer:

1.11 m/s

Explanation:

The motion of the boat is an example of accelerated motion, since the velocity is not constant. However, we don't need to find the acceleration, because we are only interested in the average velocity of the boat, which is given by:

v=\frac{d}{t}

where d is the total distance covered and t the time taken. In this problem, the boat covered a distance of d = 20 m and it takes t = 18 s, therefore the average velocity is

v=\frac{20 m}{18 s}=1.11 m/s

What is the kinetic energy of a 150 gram object moving at a velocity of 100 m/s?
Alex Ar [27]

Answer:

750 J

Explanation:

lets convert mass into kg first , 150 /1000 = 0.15 kg

kinetic energy =  \frac{mv^{2} }{2} =  \frac{0.15*100^{2} }{2}  = 750 J
