Question

Answer

Problem:

A car starts from rest and accelerates uniformly for 5 seconds. If it covers 200 m in this duration, find its acceleration and final velocity?

Solution:

Given, initial velocity (u) = 0 m/s, time (t) = 5 s, distance (s) = 200 m.

Step 1: Calculate Acceleration (a)

Using the formula, s = ut + 1/2at², we can find the acceleration:

a = 2(s - ut) / t²

Substituting the given values, we get:

a = 2(200 - 0) / 5² = 16 m/s²

Step 2: Calculate Final Velocity (v)

Using the formula, v = u + at, we can find the final velocity:

v = 0 + 16 x 5 = 80 m/s

Answer:

The acceleration of the car is 16 m/s² and the final velocity is 80 m/s.

Answer

A = 16m/s^2

v= 80m/s
