Momentum is a product of mass and the velocity of a body. The initial momentum is always equal to the final momentum during collisions between two bodies.
Therefore; M1U1 +M2U2 = M1V1+ M2V2, where m1 is the mass of tracey and m2 is the mass of jonas, while u is the initial velocity and v is the final velocity.
(32 ×0)+ (45×0) = (32 × v1) + (45 × 0.50)
0 = 32V1 + 22.5
32 V1 = -22.5
V1 = - 0.703 ( negative indicates difference in direction)
There, Tracey's speed will be 0.703 m/s
Power consumed = P = 78.0 W
Time taken = t = 10 minutes
Energy consumed = E = ?
The power, energy and time are related by the following equation:
P = E / t
Using the values, we get
78 = E/t
So,
E = 780
This means, 780 Joules of energy was used during the 10 minutes
Well Light years if a form of distance so it'll take 1.176e+14 miles to do that but that itself would take a long time
F will be the answer I guess, because 5-3=2
Answer:
Average acceleration = 6m/s²
Explanation:
Given the following data;
Initial velocity, u = 4m/s
Final velocity, v = 22m/s
Time, t = 3 seconds
To find the average acceleration;
Acceleration = (v - u)/t
Substituting into the equation, we have;
Acceleration = (22 - 4)/3
Acceleration = 18/3
Acceleration = 6m/s²
