A bus moves from rest with a uniform acceleration of 2ms(square)for the first 10s.
then it hits a brick wall, and bursts into flame. How much energy is released by the explosion of the fuel tank?
To find the displacement of the bus during the first 10 seconds, we can use the formula:
s = ut + 1/2 at^2
Where:
s = displacement (unknown)
u = initial velocity (0 m/s since the bus starts from rest)
a = acceleration (2 m/s^2)
t = time (10 s)
Plugging in the values into the equation:
s = (0 m/s)(10 s) + 1/2 (2 m/s^2)(10 s)^2
simplifying,
s = 0 m + 1/2 (2 m/s^2)(100 s^2)
s = 0 m + 1 m/s^2 * 100 s^2
s = 50 m
Therefore, the displacement of the bus during the first 10 seconds is 50 meters.
