Question

ENERGY SAVERS RACE, BRAIN BURNER. This question is about solar cars at the Chuck Norris Institute of Technology, CNIT, in Ocala, Florida. In one race, a silicon-dioxide crystal powers a car (mass = 120 kg) from rest to a top speed of 10 m/sec in a time of 1.2 sec.

Question: For what distance does the solar car accelerate to get to top speed?
a. 6.0 m
b. 150 m
c. 2.0 m
d. 9.8 m
e. 44.1 m

Answer 1

a) d = 6.0 m

Step-by-step explanation:

Since car is accelerating at uniform rate then here we can say that the distance moved by the car with uniform acceleration is given as

`d = ((v_f + v_i))/(2) * t`

here we know that

`v_f = 10 m/s`

`v_i = 0`

`t = 1.2 s`

now we will have

`d = ((10 + 0))/(2)* 1.2`

`d = 5 * 1.2`

`d = 6.0 m`
