So in this question, the velocity of the car, v of the is given as 120 multiplied by 1 minus 0 .85 power t.
00:10
Okay.
00:11
So the velocity of the car is given like this.
00:13
First one is we want to graph the function.
00:16
Second one is we want to find the acceleration of the car.
00:21
Okay.
00:22
First we will graph this function, velocity function.
00:25
We will take t and v of t as two columns first.
00:28
So t will start from 1.
00:31
Initially we start from 0.
00:33
So when t is equal to 0, v of t is equal to 120.
00:37
When t is equal to 1, v of t is equal to 100 into 1 minus 0 .85 power 1.
00:44
So which is equal to while simplifying, we will get, sorry, here 120, we will get 80...
