Prev
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 = ?
\mathrm{s=ut+\frac1 2 at^2}
a = 200/25 = 8 \mathrm{m/s^2}
