Answer:
The momentum of the plastic car is same the the momentum of the lead car.
Explanation:
Given that,
Mass of plastic car = 0.2 kg
Mass of lead = 20 kg
Time = 1 sec
Equal forces are used to push both carts
We need to calculate the momentum
Using formula of momentum
Put the value into the formula
For plastic cart,
...(I)
For lead cart,
...(II)
Divided equation (I) by equation (II)
Hence, The momentum of the plastic car is same the the momentum of the lead car.

Answer:
It's called the working distance
.
The work done on the bullet is force•distance. This is also equivalent to the energy it has leaving the muzzle (work energy theorem). This kinetic energy is (1/2)(0.006kg)(336m/s)^2=338.7J. Then 338.7J=F•0.83m
F=338.7/0.83=408N
