Hey guys,
Some questions that have been bugging me...
Mass of spacecraft is 11,000kg, and the mass of an outside astronaut is 92kg.astronaut exerts a force of 36N on spacecraft by pushing it.
Find the acceleration of the spacecraft and astronaut.
I cannot understand this question.
A 0.22 rifle bullet,travelling at 350 metres per second strikes a block of wood and penetrates to a depth of 0.13 metres
The block is clamped to a bench so that it doesn't move.
Mass of bullet is 1.8g
How much time is required for bullet to stop?
Determine the force in newtons that the bullet exerts on the block.
Any help with even understanding these questions would be greatly appreciated.:)
