Will give brainliest to the correct answer.

The acceleration of the car is

Explanation:

We are assuming rightward coordinate positive and all quantities are along this direction

We know,

where a - acceleration, v=velocity, t=time and x=displacement

multiply by dx in both sides

but we know

Therefore,

Here we integrate both sides with proper limits

x ranges from 0 to 110 as v ranges from 29 to 34

p = 0, r = 110, q = 29, s = 34

a is given as constant thus can be pulled out of the integration

Therefore,

Accelaration of the car is

Note:

Here moving to the right doesn't mean anything significant other than the fact that all quantities are pointing in that direction. Therefore obtained acceleration is also towards the right

If you know equation of motion for constant acceleration as

you can plug in values in this equation to obtain value of a

v - final velocity

u - initial velocity

s - displacement

no simpler subs form complex ones. synthesise = make

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
