Physics - Kinematics Question with Solution | TestHub
I will never forget that day. It was a day in BSF academy at Tekanpur. We were a batch of 96 police officers being taken for an intensive training in arms. Of these, 20 of us were engineers and IITians. Having studied projectile motion during our school days, we were quite keen to see it being demonstrated in case of weapons. The man showing us the demo was using a AK-47 fitted with tracer bullets. As they were fired, we could actually see them; they would emit light. First of all the man fired at the center of the
target 30 m away while firing horizontally. We could actually see the bullet moving in a parabolic path and hitting 2 cm below the target. "You see. That is what I said. For accurate firing you need to aim not at the target but slightly above."
What was the initial velocity of the bullet? If your answer is m/s. find value of .
Answer:
Solution:
The equation for projectile motion is given by:
Given the values, we have:
