A car is traveling east at 25 m/s when it turns due north and accelerates to 35 m/s, all during a time of 6.0 s. Find magnitude of cars accelrtn.

Question

A car is traveling east at 25 m/s when it turns due north and accelerates to 35 m/s, all during a time of 6.0 s. Calculate the magnitude of the car's average acceleration.

Answer 1

Average acceleration VECTOR:

 

i East

j North

 

a = (v₂ - v₁)/t = (35j - 25i)/6.0 m/s² ≅ -4.17i + 5.83j

 

Magnitude:

 

a = √(a_x² + a_y²) = √[(-4.17)² + (5.83)²] m/s² = ? m/s²
