The car pushes the ground in the backward direction and according to the third law of motion, reaction force of the ground in the forward direction acts on the car.
(b) the ground on the horse
Explanation:
The horse pushes the ground in the backward direction and, in turn, the ground pushes the horse in the forward direction, according to Newton’s third...
(b) the force of friction between the bodies is zero
(d) the bodies may be rough but they don't slip on each other.
Explanation:
Contact force F is the resultant of normal force...
Since we need equilibrium,
\(v\times A+mg=0\)
Given that, \(\vec F=\vec u\times \vec A \) and \(\vec mg\) act on the particle.
Velocity must be in direction perpendicular to plane in which gravity acts.
Thus, \(v \times A=Av\,sin\theta,\,\theta\) is the angle...
(c) remain same
EXPLANATION:
The frequency of a spring-mass system depends only on the mass and the spring constant, none of which changes in the accelerating car. So the frequency remains the...
