changes its direction at constant speed
maintains a constant linear speed
covers equal distances in equal times in a straight line
is acted upon by balanced forces

11.27N
33.81N
112.70N
338.10N
Correct answer is D
M = D x V
= 980 x 0.046 x \(\frac{3}{4}\) = 33.81kg
upthrust = mg = 33.81 x 10
= 338.1N
800N
500N
80N
50N
Correct answer is A
\(F_2 = \frac{F_1 \times A_2}{A_1} = \frac{40 \times 200}{10} = 800N\)
