Acceleration is defined as rate of change in velocity
So we can write its formula as

here we know that
= final velocity = 56 m/s
= initial velocity = 7.6 m/s
t = time interval to change the velocity = 3 s
now we will plug in all values in the above equation



so here roller coaster will accelerate at rate of 16 m/s^2 and hence correct answer is "option d"
Answer:
62.7 VA
Explanation:
The apparent power (power supplied by the source) of an AC circuit is determined by

The impedance(Z) depends on the frequency, but in this case it is given to us that it is 102 ohms at this frequency.
So:
