Section A · multiple choice
- 1.
How long does a body take to go from 3 m/s to 33 m/s with acceleration 3 m/s²?
- 20 s
- 11 s
- 9 s
- 10 s
Answer
(d) 10 s
t = (v − u)/a
- 2.
A car starts at 15 m/s and accelerates uniformly at 10 m/s² for 9 s. The distance covered is:
- 405 m
- 135 m
- 540 m
- 945 m
Answer
(c) 540 m
s = ut + ½at²
- 3.
A car moving at 8 m/s brakes with a deceleration of 4 m/s². Its stopping distance is:
- 2 m
- 4 m
- 16 m
- 8 m
Answer
(d) 8 m
v² = u² − 2as with v = 0
Section B · short answer
- 4.
A ball is thrown vertically upwards at 70 m/s. Find (a) the maximum height, (b) the time to reach it, (c) the total time in the air. (Take g = 10 m/s².)
Answer
(a) 245 m; (b) 7 s; (c) 14 s
v² = u² − 2gh; v = u − gt
- 5.
A car moving at 10 m/s is brought to rest in 50 m. Find the deceleration and the time taken.
Answer
1 m/s²; 10 s
a = u²/2s; t = u/a
Section C · long answer
- 6.
A car passes a stationary police jeep at a constant 6 m/s. At that instant the jeep starts from rest with acceleration 2 m/s². (a) When does it catch the car? (b) How far has it travelled? (c) What is its speed then?
Answer
(a) 6 s; (b) 36 m; (c) 12 m/s
6t = ½ × 2 × t²
