Assertion : If a body is thrown upwards, the distance covered by it in the last second of upward motion is about \(5 \mathrm{~m}\) irrespective of its initial speed
Reason : The distance covered in the last second of upward motion is equal to that covered in the first second of downward motion when the particle is dropped.
141878 Assertion: Two balls of different masses are thrown vertically upward with same speed. They will pass through their point of projection in the downward direction with the same speed. Reason: The maximum height and downward velocity attained at the point of projection are independent of the mass of the ball.
141879
Assertion: The two bodies of masses \(M\) and \(m\) \((M>m)\) are allowed to fall from the same height. If the air resistance for each be the same then both the bodies will reach the earth simultaneously.
Reason: For same air resistance, acceleration of both the bodies will be same.
