Q. A ball is dropped from a height of 45 meters. How long will it take to hit the ground? (Assume g = 9.8 m/s²)
A.
2 s
B.
3 s
C.
4 s
D.
5 s
Solution
Using the formula t = √(2h/g), where h = 45 m and g = 9.8 m/s², we get t = √(2 * 45 / 9.8) ≈ 3.06 s.
Q. An object moves in a straight line with a constant acceleration of 3 m/s². If its initial velocity is 5 m/s, what will be its velocity after 4 seconds?
A.
5 m/s
B.
11 m/s
C.
17 m/s
D.
23 m/s
Solution
Using the formula v = v_i + at, where v_i = 5 m/s, a = 3 m/s², and t = 4 s, we get v = 5 + (3 * 4) = 17 m/s.
