Question

a car initially at rest starts moving with a constant acceleration of 0.5m/s and travels a distance of 25m. find its initial velocity and time taken???

Answer 1

✯Question:

• A car initially at rest starts moving with a constant acceleration of 0.5m/s and travels a distance of 25m. Find it's final velocity and time taken?

✯Given:

• Initial velocity (u) = 0m/s
• Acceleration (a) = 0/5m/s²
• Distance (S) = 25m

✯To find:

• final velocity (v)
• Time taken (t)

✯Solution:

• v² = u² + 2as
• v² = 0² + 2(0.5) × 25
• v² = 25
• v = √25
• Final velocity = 5m/s

✵Final velocity is 5m/s

• v = u + at
• 5 = 0 + 0.5t
• 0.5t = 5
• t = 5÷0.5
• t = 10s

✵Time taken is 10s

Answer 2

Answer:

✯Question:

A car initially at rest starts moving with a constant acceleration of 0.5m/s and travels a distance of 25m. Find it's final velocity and time taken?

✯Given:

Initial velocity (u) = 0m/s

Acceleration (a) = 0/5m/s²

Distance (S) = 25m

✯To find:

final velocity (v)

Time taken (t)

✯Solution:

v² = u² + 2as

v² = 0² + 2(0.5) × 25

v² = 25

v = √25

Final velocity = 5m/s

✵Final velocity is 5m/s

v = u + at

5 = 0 + 0.5t

0.5t = 5

t = 5÷0.5

t = 10s

✵Time taken is 10s
