Two mass points

Two mass points start moving simultaneously in the same direction from the same location: the first point moves uniformly at a speed of 50 cm/s, and the second point moves with uniform acceleration from rest at an acceleration of 10 cm/s².

Determine:
a) the time at which both mass points have the same speed,
b) the time at which both mass points have travelled the same distance.

Final Answer:

t1 =  5 s
t2 =  10 s

Step-by-step explanation:

v1=50 cm/s v2=0 cm/s a2=10 cm/s2  v1 = a2 t1  t1=v1/a2=50/10=5 s
 v1   t2 = 21   a2   t2  50 t2 = 0.5   10   t22  50 = 5   t2  t2=50/5=10 s
