Question

A car starts from rest and accelerates at 5 m/s² for 10 seconds. How far has it traveled at 10 s?

A. 25 m

B. 50 m

C. 75 m

D. 100 m

Answer 1

The car has traveled 250 meters at 10 seconds.

Step-by-step explanation:

The car starts from rest and accelerates at a rate of 5 m/s² for 10 seconds. To find the distance traveled at 10 seconds, we can use the equation:

d = v0t + (1/2)at2

Where:
d = distance traveled
v0 = initial velocity (rest, so 0 m/s)
t = time (10 seconds)
a = acceleration (5 m/s²)

Plugging in the values, we get:
d = 0(10) + (1/2)(5)(10)2
d = 0 + (1/2)(5)(100)
d = 0 + (1/2)(500)
d = 0 + 250
d = 250 meters

Therefore, the car has traveled 250 meters at 10 seconds.
