Question

A car starts from rest. If its acceleration is 1.5 m/s2 in 1.5 seconds, then calculate the

distance travelled by it.
​

Answer 1

1.6875 m

Step-by-step explanation:

Here, we are given that,

• Initial velocity (u) = 0 (as it starts from rest)
• Acceleration (a) = 1.5 m/s²
• Time taken (t) = 1.5 s

Then,

• Distance (s) = ?

By using the second equation of motion,

★ s = ut + ½at²

• s is distance
• u is initial velocity
• t is time
• a is acceleration

⇒ s = 0(1.5) + ½ × 1.5 × (1.5)²

⇒ s = ½ × 1.5 × 2.25

⇒ s = ½ × 1.5 × 2.25

⇒ s = ½ × 3.375

⇒ s = 1.6875 m

∴ Distance travelled by it is 1.6875 m.
