Answer: Velocity=8.26m/s

Explanation:

Acceleration=Finial velocity (V) - Initial velocity (u) ÷ Time

that is, a=v-u/t

a=1.2m/s², v=?, u=5.5m/s, t=2.3s

From a=v-u/t, make v the subject of the formula

v=at + u

v=(1.2* 2.3) + 5.5

v=2.76+5.5

v=8.26m/s

This time particle A starts from rest and accelerates to the right at 65.5 cm/s
FrozenT [24]

Answer:

t = 4 s

Explanation:

As we know that the particle A starts from Rest with constant acceleration

So the distance moved by the particle in given time "t"

d = v_i t + \frac{1}{2}at^2

d = 0 + \frac{1}{2}(65.5)t^2

d_1 = 32.75 t^2 cm

Now we know that B moves with constant speed so in the same time B will move to another distance

d_2 = 44 \times t

now we know that B is already 349 cm down the track

so if A and B will meet after time "t"

then in that case

d_1 = 349 + d_2

32.75 t^2 = 349 + 44 t

on solving above kinematics equation we have

t = 4 s
