a) Explain the meaning of the following equation of motion: v = u + at

1.	a) Explain the meaning of the following equation of motion: v = u + at where the symbols have their usual meanings. b) A body starting from rest travels with uniform acceleration. If it travels 100 m in 5 s what is the value of acceleration?
Answer» a) v = u + at is the first equation of motion. Where, v is the final velocity u is the initial velocity a is the acceleration t is the time taken b) Initial velocity, u = 0 m/s Time, t = 5s Distance, s = 100 m Acceleration, a = ? s = ut + 1/2at² a = 200/25 = 8 m/s²

Answer»

a) v = u + at is the first equation of motion.

Where,

v is the final velocity

u is the initial velocity

a is the acceleration

t is the time taken

b) Initial velocity,

u = 0 m/s

Time, t = 5s

Distance, s = 100 m

Acceleration, a = ?

s = ut + 1/2at²
a = 200/25 = 8 m/s²
