A particle starts from rest with a constant acceleration. At a time t second, the speed is found to be 100 m/s and one second later the speed becomes 150 m/s. The acceleration a and the distance d travelled during the (t + 1)th second respectively, are
- a)a = 50 m/s2; d = 125 m
- b)a = 100 m/s2: d = 100 m
- c)ci = 100 m/s2: d = 125 m
- d)a = 50 m/s2; d = 100 m
Correct answer is option 'A'. Can you explain this answer?

Verified Answer
A particle starts from rest with a constant acceleration. At a time t ...
Velocity at time t is
100 = a. t ...(i)
and velocity at time (t + 1) is
150 = a (t + 1) ...(ii)
Subtracting (i) from (ii). a = 50 m/s2
During the interval t and (t + 1) second
time elapsed = 1 s
intial velocity u = 100 m/s
final velocity v = 150 m/s
100 = a. t ...(i)
and velocity at time (t + 1) is
150 = a (t + 1) ...(ii)
Subtracting (i) from (ii). a = 50 m/s2
During the interval t and (t + 1) second
time elapsed = 1 s
intial velocity u = 100 m/s
final velocity v = 150 m/s

To solve this question, we can use the equations of motion. Let's break down the problem into smaller parts:
1. Initial conditions:
- The particle starts from rest, which means its initial velocity (u) is 0 m/s.
2. Speed at t seconds:
- At time t, the speed of the particle is given as 100 m/s.
3. Speed at (t+1) seconds:
- One second later, at (t+1) seconds, the speed of the particle is given as 150 m/s.
4. Finding acceleration:
- We can use the equation v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time taken.
- Using the information given, we can substitute the values:
- At t seconds: 100 = 0 + a * t
- At (t+1) seconds: 150 = 0 + a * (t+1)
- Subtracting the first equation from the second equation, we get:
- 150 - 100 = a * (t+1) - a * t
- 50 = a * 1
- Therefore, the acceleration (a) is 50 m/s^2.
5. Finding distance travelled in (t+1)th second:
- We can use the equation v = u + at to find the distance travelled in the (t+1)th second.
- Since the particle starts from rest, the initial velocity (u) is 0 m/s.
- Plugging in the values, we have:
- 150 = 0 + 50 * (t+1)
- 150 = 50t + 50
- 100 = 50t
- t = 2 seconds
- Therefore, the distance travelled in the (t+1)th second is:
- d = ut + (1/2)at^2
- d = 0 + (1/2) * 50 * (2)^2
- d = 0 + 50 * 4
- d = 200 m
So, the correct answer is option A:
a = 50 m/s^2 and d = 125 m.
1. Initial conditions:
- The particle starts from rest, which means its initial velocity (u) is 0 m/s.
2. Speed at t seconds:
- At time t, the speed of the particle is given as 100 m/s.
3. Speed at (t+1) seconds:
- One second later, at (t+1) seconds, the speed of the particle is given as 150 m/s.
4. Finding acceleration:
- We can use the equation v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time taken.
- Using the information given, we can substitute the values:
- At t seconds: 100 = 0 + a * t
- At (t+1) seconds: 150 = 0 + a * (t+1)
- Subtracting the first equation from the second equation, we get:
- 150 - 100 = a * (t+1) - a * t
- 50 = a * 1
- Therefore, the acceleration (a) is 50 m/s^2.
5. Finding distance travelled in (t+1)th second:
- We can use the equation v = u + at to find the distance travelled in the (t+1)th second.
- Since the particle starts from rest, the initial velocity (u) is 0 m/s.
- Plugging in the values, we have:
- 150 = 0 + 50 * (t+1)
- 150 = 50t + 50
- 100 = 50t
- t = 2 seconds
- Therefore, the distance travelled in the (t+1)th second is:
- d = ut + (1/2)at^2
- d = 0 + (1/2) * 50 * (2)^2
- d = 0 + 50 * 4
- d = 200 m
So, the correct answer is option A:
a = 50 m/s^2 and d = 125 m.
