To find the kinetic energy (K.E), we can use the formula:
K.E = 1/2 * m * v^2
Where:
m = mass of the Ford
v = velocity of the Ford
Given:
mass of the Ford (m) = 1500 kg
velocity of the Ford (v) = 21 m/s
To find the K.E when the speed of the Ford is tripled, we need to calculate the new velocity (v_new) and use it in the formula.
New velocity (v_new) = 3 * v
= 3 * 21 m/s
= 63 m/s
Now, we can substitute these values in the formula:
K.E = 1/2 * m * v_new^2
= 1/2 * 1500 kg * (63 m/s)^2
Calculating the value:
K.E = 0.5 * 1500 kg * (63 m/s)^2
= 0.5 * 1500 kg * 3969 m^2/s^2
= 2976750 Joules
Therefore, the kinetic energy (K.E) when the speed of the Ford is tripled is 2,976,750 Joules.
If a Ford weighs 1500kg and is traveling at a speed of 21m/s, what is the K.E if the speed of the Ford is tripled
