Questions and Answers

What is the value of the gravitational constant (G) in the provided scenario?

6.67 x 10^-11 Nm2/kg2 (correct)

4.002 x 10^-7 N

5.34 x 10^-9 m/s2

According to Newton’s first equation of motion, what is the formula to calculate velocity (v)?

v = u/t + a

v = u x a

v = u + at (correct)

v = a/t

If Mahendra starts with an initial velocity of zero and experiences an acceleration of 5.34 x 10^-9 m/s2, what will be his velocity after 1 second?

6.67 x 10^-11 Nm2/kg2

5.34 x 10^-9 m/s (correct)

4.002 x 10^-7 N
