How far will a body move in 4 seconds if uniformly accelerated from rest at the rate of 2 ms-2?
32m
24m
16m
1.2m
5m
Correct answer is C
S = vt + 1/2 at2 = 0 + 1/2 x 2 x 42 = 16m
0o
30o
45o
60o
90o
Correct answer is B
0.10N
0.25N
0.30N
0.40N
0.50N
Correct answer is D
Weight of object = mg
= \(\rho vg\) = 2.5 x 10\(^3\) x 2 x 10\(^{-5}\) x 10 = 0.5N;
Upthrust = weight of displaced fluid = \(\rho_{water} vg\)
= \(\frac{1.0 \times 10^3 \times 2 \times 10^{-5} \times 10}{2}\) = 0.1N
∴Reading = 0.5 – 0.1 = 0.4N
25s
7.1s
10.0s
50.0s
100.0s
Correct answer is C
S = ut + 1/2at2
25 = 0 + 1/2 x 0.5t2
T = 10s
