A dragster going 15m/s increases its velocity to 25 m/s north in 4 seconds.

1 answer:

3 0

Initial speed, v₁ = 15 m/s
Final speed, v₂ = 25 m/s
Duration of the acceleration, t = 4 s

Calculate the acceleration.
a = (v₂ - v₁)/t
= (25-15 m/s)/(4 s)
= 2.5 m/s²

Answer: 2.5 m/s²

Vector ~A has a magnitude of 29 units and points in the positive y-direction. When vector ~B is added to ~A, the resultant vecto

timurjin [86]

Answer:

The magnitude of vector B is 43 units and it points in the negative y-direction.

Explanation:

Resultant of vectors = vector sum of all the vectors

Vector A = 29j

Vector B = ?

Resultant of vector A and B = R = -14j

R = A + B

-14j = 29j + B

B = -14j - 29j = - 43j

Hence, the magnitude of vector B is 43 units and it points in the negative y-direction.
