Question

A car moving on a straight road at 5 m/s. It is accelerated at 3 m/s^2. What will be its velocity after 4 seconds ?​

Answer 1

Explanation:

v=u+at

v=5+(3×4)

v=17m/s

Answer 2

Given :-

• Initial velocity = 5 m/s
• Acceleration = 3 m/s²
• Time = 4 sec

To Find :-

• Final Velocity

Solution :-

• u = 5 m/s
• a = 3 m/s²
• t = 4 sec

Substituting the value in 1st equation of motion :-

➩ v = u + at

➩ v = 5 + 3 × 4

➩ v = 5 + 12

➩ v = 17 m/s

Final velocity = 17 m/s
