The momentum of the car:
p = m*V
m = F/g = 15 000 / 10 = 1 500 kg
V = 90 km/h = 25 m/s
p = 1 500 * 25 = 37 500 kg*m/s
Answer:
4.71m/s
Explanation:
Given parameters:
Distance covered = 40.5m
Time taken = 8.6s
Unknown:
Speed = ?
Solution:
The speed of Samantha is the distance divided by the time taken.
Speed =
Now insert the parameters;
Speed = = 4.71m/s
It can push or pull an object.... I think.
