A body starts at `t=0` with velcoity `u` and travels along a straight linge. The body has a constant acceleration(a). Draw the acceleration-time graph from `t=0` to `t=10 s` for the following cases:
a. `u=8 ms^(-1)`, a=2s^(-2)`
b. `u=8 ms^(-1)`, a=-2 ms^(-2)`
c. `u=- 8ms^(-1)` ,a=2 ms^(-2)`
d. `u=-8ms^(-1)` ,a=-2 ms^(-2)`.

Explanation

To solve the problem of drawing the acceleration-time graphs for the given scenarios, we will analyze each case step by step.

### Step 1: Understanding the Parameters
We have a body that starts with an initial velocity \( u \) and has a constant acceleration \( a \). We need to draw the acceleration-time graph from \( t = 0 \) to \( t = 10 \) seconds for four different cases.

### Step 2: Case Analysis
We will analyze each case one by one.
