D. If the velocity of particle change from 4m/sec to 10 meter/sec in 3 sec then calculate th
distance of a particle covered in 10 seconds.
Answers
Answer:
If the velocity of the particle changes at a constant rate, then this rate is called the constant acceleration. ... If the particle has a velocity of 4 m/s initially (at t=0) and has a constant ... rate of change) from 5 m/s to 2 m/s over one second, its constant acceleration is −3 m/s2. ... After one second, the car's velocity is 2509−10 m/s.

If the velocity of particle change from 4m/s to 10 m/s in 3 sec then calculate the distance of a particle covered in 10 seconds.
u = 4m/s ; v = 10m/s ; t = 3 ; s = ?
v = u + at
10 = 4 + 3a
10 - 4 = 3a
3a = 6
a = 2m/s²
Now,
We have to find the value of distance(s)
s = ut + 1/2 at²
s = 4 × 3 + 1/2 × 2 × 3 × 3
s = 12 + 9
s = 21m
In 3 sec it covers 21m
Then in 1 sec
21/3 = 7m/s
In 10sec
= 7 × 10
= 70m
Hence Verified
