If you borrow your mom's car to drive 128 m to the store, but you go cruising
1 answer:
Answer:
v = 0.349 m/s
Explanation:
If you borrow your mom's car to drive 128 m to the store, but you go cruising instead and drive a total distance of 1256 m in 3600s.
We need to find your speed during the trip. It is equal to the total distance divided by time taken.
He has done cruising instead and drive a total distance of 1256 m.
So,
So, the speed of the person during the trip is 0.349 m/s.

Answer:
Explanation:
In order to calculate the angular momentum of the particle you use the following formula:
(1)
r is the position vector respect to the point (0 , 5.0), that is:
r = 0m i + 5.0m j (2)
p is the linear momentum vector and it is given by:
(3)
the direction of p comes from the fat that the particle is moving along the i + j direction.
Then, you use the results of (2) and (3) in the equation (1) and solve for L:
The angular momentum is -30 kgm^2/s ^k
