Question

Winston the Corgi was walking at 1 m/s when he

noticed a friend Corgi and sped up uniformly at 2
m/s/s over a distance of 15 meters. How many
seconds did the acceleration
take him?

Answer 1

Winston the Corgi took 7 seconds to accelerate.

Step-by-step explanation:

To determine the time it took for Winston the Corgi to accelerate, we can use the formula:

v = u + at

where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time.

Given that Winston accelerated uniformly at 2 m/s2 and the initial speed was 1 m/s, we can substitute the values into the formula:

15 = 1 + 2t

Now, we can rearrange the equation to solve for t:

2t = 14

t = 7 seconds

Therefore, it took Winston 7 seconds to accelerate.
