The kinetic energy of the bicycle can be calculated using the formula: KE = 1/2 * mass * velocity^2. Plugging in the values, KE = 1/2 * 14 kg * (3 m/s)^2 = 63 J. The kinetic energy of the bicycle is 63 Joules.
KE = 1/2*mass * velocity^2 KE = 1/2(14 kg)(3 m/s)^2 = 63 Joules
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.
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.
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.
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
Kinetic energy is half the mass times the square of the speed. Joules = (14/2) x 32 = 7 x 9 = 63 joules.
KE = 1/2*mass * velocity^2 KE = 1/2(14 kg)(3 m/s)^2 = 63 Joules
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 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)
