Answer:
Explanation:
Given:
- initial speed of the car,
- time taken to realize the need of braking,
<u>Distance travelled during the time span:</u>
Actually the distance travelled before stopping the car will be greater than this distance, because after the application of brakes the car will take some time to come to rest.

Answer:
v = 35.11 m / s, θ = 20º north of east
Explanation:
This is a compound problem of relative velocities, we can use the Pythagorean theorem to find the modulus of the resulting velocity
v² = v₁² + v₂²
where the eastward velocity is v₁=33 m/s and the northward velocity
v₂=12 m / s
v =
v = 35.11 m / s
the direction of this velocity can be found with the uses of trigonometry
tan θ = v₂ / v₁
θ = tan⁻¹ v₂ / v₁
θ = tan⁻¹ 12/33
θ = 20º
this angles is north of east
