Answer:
The Momentum Calculator uses the formula p=mv, or momentum (p) is equal to mass (m) times velocity (v). The calculator can use any two of the values to calculate the third.
Explanation:
Answer:
t = 3.44 s
Explanation:
We are given;
Fired from rest, and so; u = 0 m/s
Final speed; v = 170 m/s
Height above flat ground; y_o = 58 m
Height at starting point; y = 0 m
Thus, from Newton's equation of motion, we have;
y - y_o = ut - ½gt²
(since it's motion is against gravity)
Plugging in the relevant values, we have;
0 - 58 = 0 - (½ × 9.8 × t²)
-58 = -4.9t²
t² = 58/4.9
t = √(58/4.9)
t = 3.44 s

Answer:
Change in momentum is
Solution:
The momentum of any body is the product of its mass and the velocity associated with the body and is generally given by:
Now, as per the question:
Mass of the car, M = 1500 kg
The velocity in the east direction,
The velocity in the north direction,
Now, the momentum of the car in the east direction:
Now, the momentum of the car in the north direction:
Change in momentum is given by:
Now,
(Since, )
