Acar starts from rest and travels for t1 seconds with a uniform acceleration a1. the driver then applies the brakes, causing a uniform acceleration a2. if the brakes are applied for t2 seconds, determine the following. answers are in terms of the variables a1, a2, t1, and t2. (a) how fast is the car going just before the beginning of the braking period?

Explanation:

It is given that,

Initially the car is at rest and travels for t₁ seconds with a uniform acceleration a₁. The driver then applies the brakes, causing a uniform acceleration a₂, If the brakes are applied for t₂ seconds.

We need to find the speed of the car just before the beginning of the braking period.

Using the formula of acceleration. It is given by :

u = 0

So, just before the beginning of the braking period the speed of the car is . Hence, this is the required solution.

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.
