Q1. Over two back-to-back intervals of 10 s each, a trolley travels 48 m and then 36 m. What kind of motion does this show?
- A.Rest
- B.Uniform motion
- C.Non-uniform motion
- D.Uniform motion because the time intervals are equal
Answer: C. Non-uniform motion
Speed in interval 1 = 48/10 = 4.8 m/s; speed in interval 2 = 36/10 = 3.6 m/s. Unequal distances in equal times mean the speed changes, so the motion is non-uniform.
Q2. While timing a cyclist, Saanvi finds it goes 72 m in 2 s and 72 m in the next equal interval of 2 s. Is the motion uniform?
- A.Cannot be decided from the data
- B.Non-uniform motion
- C.Uniform motion
- D.Accelerated motion
Answer: C. Uniform motion
Speed in interval 1 = 72/2 = 36 m/s; speed in interval 2 = 72/2 = 36 m/s. Equal distances (72 m) in equal times (2 s) give the same speed, so the motion is uniform.
Q3. Moving uniformly, a cyclist clocks 45 m each 2 s. What distance will it cover in 6 s of such travel?
- A.90 m
- B.51 m
- C.135 m
- D.180 m
Answer: C. 135 m
Number of 2-second intervals in 6 s = 6/2 = 3. At 45 m per interval, distance = 45 * 3 = 135 m.
