QUESTIONS 48. A car accelerates uniformly from rest at 5ms"2. Determine its speed after 10s.
WAEC 2006 (Ans: 50.0ms"1)
Solutions
Uniform acceleration a, = 5m/s²
Speed v=?
Initial velocity u ,= 0m/s
time ,t = 10s
Uniform acceleration = change in displacement/time
v = u + at
v = 0 + 5 x 10
v = 0 + 50
v = 50m/s
