Answer:
i think it's 50 N
i might be wrong though not sure
C ,because kinetic energy is stored and there is energy needed for the ball to keep bouncing
If you use the same force to push a truck and a car, the car will have more acceleration than the truck, because the car has less mass.
Answer:
a) The magnitude of the car's total displacement (T) from the starting point is T = 82.67 Km
b) The angle (θ) from east of the car's total displacement measured from the starting direction is θ = 40.88 °
Explanation:
Attached you can see a diagram of the problem.
a) Find the magnitude of the vector T that goes from point A to point D (see the diagram).
The x and y components of this vector are
The magnitude of the vector is find using the pythagoras theorem:
, being a, b and c the 3 sides of the triagle that forms the vector:
Replacing the values
b) Find the angle θ that forms the vector T and the vector AB (see diagram).
To find this angle you can use the inverse tangent
θ
θ
θ=40.88°
