Are there any situations in which we cannot apply Newton’s laws of motion? Is there any alternative for it?

Correct Answer - D `vec(F)_(1)+t=0` `(5-t)hat(i)+[t^(2)-50+t^(2)]hat(j)=0` t = 5

No. In projectile motion, the horizontal and vertical motion are independent of each other because both motions don’t affect each other.

Statement: The rate of change of linear momentum of a rigid body is directly proportional to the applied (external unbalanced) force and takes place in the direction of force. \(\overset\rightarrow{F}=\frac{d\overset\rightarrow{p}}{dt}\) Where, \(\overset\rightarrow{F}\) = Force...

Forces of action and reaction always act on different bodies, hence they never cancel each other.

Correct option is: (C) 5.00 Given, F = 5N W = 9.80 a = ? W = mg \(9.80 = m \times 9.8\) m = 1 kg F = ma \(5 = 1 \times a\) \(a = 5 m/s^2\)

Correct option is: (B) (II) is correct.
