Answer» on✯A car initially at rest starts moving with a constant ACCELERATION of 0.5m/s and travels a distance of 25m. Find the velocity and TIME TAKEN?✬Given✬Initial velocity (u) = 0m/sAcceleration (a) = 0.5m/sDistance travelled (S) = 25m☆To find☆Final velocity (v)Time taken (t)✮Solution✮From equation of motion:v² = u² + 2asv² = (0)² + 2(0.5)(25)v² = 25v = √25v = 5m/s➺Final Velocity (v) = 5m/sFrom equation of motion:v = u + at5 = 0 + 0.5(t)t = 5 ÷ 0.5t = 10s➺Time taken (t) = 10s |
