What is the kinetic energy of a bicycle with a mass of 14kg traveling at a velocity of 3 ms?
KE = 1/2*mass * velocity^2 KE = 1/2(14 kg)(3 m/s)^2 = 63 Joules
While in empty space an astronaut throws a ball at a velocity of 14 ms. What will the velocity of the ball be after it has traveled 2 meters?
The velocity of the ball will remain constant at 14 m/s since there are no external forces acting on it to change its velocity in empty space.
Car is traveling at a constant speed of 12 m s when the driver accelarates the car reaches a speed of 26 m s in 6 s what is the average accelaration of the car?
The change in velocity is 26 m/s - 12 m/s = 14 m/s. The time taken for this change is 6 seconds. Therefore, the average acceleration is (change in velocity / time) = 14 m/s / 6 s = 2.33 m/s^2.
Mass weight of 14 electrons 14 protons 12 neutrons?
The mass of an electron is approximately 9.11 x 10^-31 kg, the mass of a proton is about 1.67 x 10^-27 kg, and the mass of a neutron is also about 1.67 x 10^-27 kg. Therefore, the total mass of 14 electrons would be 14 * 9.11 x 10^-31 kg, the total mass of 14 protons would be 14 * 1.67 x 10^-27 kg, and the total mass of 12 neutrons would be 12 * 1.67 x 10^-27 kg. You can calculate the exact values by multiplying the respective masses by the number of particles.
What is the relationship between work and motion?
1) Work input = Force * distance 2) Force = mass*acceleration 3) Acceleration = (Vf - Vi) ÷ time 4) Force = mass * [(Vf - Vi) ÷ time] 5) Distance = Average velocity * time 6) Average velocity = (Vf + Vi) ÷ 2 7) Distance = [(Vf + Vi) ÷ 2] * time Eq#4 * EQ #7 8) Work input = mass * [(Vf - Vi) ÷ time] * [(Vf + Vi) ÷ 2] * time Time cancels 9) Work input = mass * (Vf - Vi) * (Vf + Vi) ÷ 2 10)(Vf - Vi) * (Vf + Vi) = Vf^2 - Vi^2 11)Work input = mass * [Vf^2 - Vi^2] ÷ 2 12)Work input = mass *( Vf^2 ÷ 2) - mass * (Vi^2 ÷ 2) 13)Kinetic energy = ½ mass *velocity ^2 14) Change in KE = (½ mass * Vf ^2) - (½ mass * Vi ^2) Equation #12 = Equation #14 so 15)Work input = Change in KE 16)Work input = ∆ KE
What is the kinectic energy of a bicycle with a mass of a 14 kg traveling at a valocity of 3 ms?
Kinetic energy is half the mass times the square of the speed. Joules = (14/2) x 32 = 7 x 9 = 63 joules.
What is the kinetic energy of a bicycle with a mass of 14kg traveling at a velocity of 3 ms?
KE = 1/2*mass * velocity^2 KE = 1/2(14 kg)(3 m/s)^2 = 63 Joules
20kg mass falls 10m what is maximum velocity?
Starting from rest, the final velocity in a fall of 10 meters is 14 meters per second. Without air resistance, the mass or weight of the falling object makes absolutely no difference.

The velocity of the ball will remain constant at 14 m/s since there are no external forces acting on it to change its velocity in empty space.
A bicycle leaves town at 14 mph at 8am a car leaces at llam traveling in the same direction at 40 mph how many minutes after 11am is it when the car overtake the bicycle?
The bicycle has a lead of (11 - 8) = 3 hours x (14 miles per hour) = 42 miles.After the car starts out, it closes the bike's lead at the rate of (40 - 14) = 26 miles per hour.To close the lead of 42 miles, it takes (42/26) = 1.6154 hours = 1hr 36min 55.4secThe car overtakes the bike at 12:36:55.4 PM = 96.923 minutes after 11 AM.(rounded)
