Question

a body is moving with a velocity of 15/ s if the motion is uniform what Will be it's velocity after 10s

Answer 1

in uniform motion , acceleration is zero ..
so , u = 15 m/s
a =0
t1 = 0 sec
t2 = 10 s
v = ?


using 2nd equation of motion,
v = UT+ 1/2at2
v= 15×(10-0) + 1/2×0×(10-0)2
v = 15×10 = 150 m/s

I hope this answer is correct...
