A body of mass 100Kg is moving with a velocity 1m/s the frictional for...
Given:
- Mass of the body, m = 100 Kg
- Initial velocity, u = 1 m/s
- Frictional force, f = 5 kg wt = 5 x 9.8 N (1 kg wt = 9.8 N)
- Applied force, F = 50 N
- Time, t = 60 s
To find:
- Final velocity, v
Solution:
1. We know that the net force acting on the body is given by:
F_net = F_applied - F_friction
2. Using the above formula, we can find the net force acting on the body:
F_net = 50 N - 5 x 9.8 N = 0.2 N
3. We can now use the formula for acceleration:
a = F_net / m
4. Substituting the values, we get:
a = 0.2 N / 100 Kg = 0.002 m/s^2
5. We can now use the formula for velocity:
v = u + at
6. Substituting the values, we get:
v = 1 m/s + 0.002 m/s^2 x 60 s = 1.12 m/s
7. Hence, the final velocity of the body after one minute is 1.12 m/s, which is approximately equal to 1.6 m/s (option 3).
Therefore, the answer is option '3'.

6. Substituting the values, we get:
v = 1 m/s + 0.002 m/s^2 x 60 s = 1.12 m/s

Therefore, the answer is option '3'.
