When a bus suddenly takes a turn, the passengers are thrown outwards because of
Inertia of motion
Acceleration of motion
Speed of motion
Both (b) and (c)
“Momentum and changes in momentum are not always in same direction”. Explain by suitable example.
An object with a mass $10 \,kg$ moves at a constant velocity of $10 \,m/sec$. A constant force then acts for $4\, second$ on the object and gives it a speed of $2\, m/sec$ in opposite direction., the impulse acting on the object is ......... $newton \times \sec $
A batsman deflects a ball by an angle of $45^o$ without changing its initial speed which is equal to $54\; km/h$. What is the impulse imparted to the ball in $kg\;m/s$? (Mass of the ball is $0.15 \;kg.)$
A small mass $m$ is launched from the top of a cliff with speed Vat an angle of $30^o$ above the horizontal. When the mass reaches the ground, its velocity is directed at $45^o$ below the horizontal. Which one of the following choices is the magnitude of the total impulse that was imparted to the mass during its flight ? Ignore air resistance
Newton's third law of motion leads to the law of conservation of
