Answer:
√(1025) m/s or around 32 m/s
Explanation:
Given:
U= 5 m/s (initial speed)
a= 10 m/s^2 (acceleration)
S= 50 m (distance travelled)
(Always write all the given terms to save your time)
You must remember these equations:
V= U + aT
S= UT + 1/2aT^2
V^2= U^2 + 2aS
V is final speed and T is Time of motion.
So we have U, a and S; and we need V
Thus use the last equation.
V^2 = U^2 + 2aS
=> V^2 = 5^2 + 2×10×50
=> V^2 = 25 + 1000
=> V^2 = 1025
=> V = √(1025) m/s
We know 32^2 is 1024.
Hence √(1025) is around 32 m/s.
Hope it helps...
