Answer:
The final velocity of the car is 26.65 m/s.
Explanation:
Given;
acceleration of the racecar, a = 6.5 m/s²
initial velocity of the car, u = 0
time of motion, t = 4.1 s
The final velocity of the car is given by;
v = u + at
where;
v is the final velocity of the car
suvstitute the givens
v = 0 + (6.5)(4.1)
v = 26.65 m/s.
Therefore, the final velocity of the car is 26.65 m/s.

Answer:
Explanation:
The equation for momentum is p = mv; therefore,
p1 = 50(4) so
p1 = 200
p2 = 50(5) so
p2 = 250
The impulse, the change in the momentum, is 50, going in the same direction.
Answer:
≅279.02 N, 36° 15' from North to East
Explanation:
You can the theory of triangle of forces to find the answer.
Two forces are acting perpendicular to each other so use Pythagoras theorem to find the magnitude of the resultant force(x).
x² = 225² + 165²
x = 279.02 N
To find the direction use the same force triangle,

Frequency: The rate at witch something occurs or is repeated over particular period of time or in a given sample.
