The acceleration is 4 m/s² in the direction of motion
Explanation:
A car speeds up from rest to +16 m/s in 4 s
To find the acceleration:
1. Find the best rule contains initial velocity "u", final velocity "v", time "t"
and acceleration "a"
2. Substitute the values of u , v and t in the rule
3. Find the acceleration a
→ v = u + a t
→ u = 0 m/s , v = + 16 m/s , t = 4 seconds
→ 16 = 0 + a(40
→ 16 = 4 a
Divide both sides by 4
→ a = 4 m/s² in the direction of motion
The acceleration is 4 m/s² in the direction of motion
