2.5ms-2
5.0ms-2
7.5ms-2
10.0ms-2
Correct answer is A
a = \(\frac{F}{m}\)
= \(\frac{60000 -(4800 \times10)}{4800}\)
= 2.5ms-2
11.36km
12.36km
13.00km
14.36km
Correct answer is A
R = \(\sqrt {5^2 + 8^2 - 2 \times 5 \times 8 \times cos 120^o}\)
R = \(\sqrt{129}\)
= 11.36km
81.00kg
9.00kg
0.90kg
0.09kg
Correct answer is C
Thrust = force x time
thrust = \(\frac{m(v - u)}{t}\) x \(\frac{t}{1}\)
270 = m(300 - 0)
m = 0.90kg
Which of the following units is equivalent to kgms-1?
Ns-1
Nms-1
Ns
Js-1
Correct answer is C
kgms-1 = \(\frac{mass}{distance}\)
since, F = ma = kgms-1 = N
kgms-1 = Ns
\(^{43}_{22}X\)
\(^{22}_{43}X\)
