Answer:
The average force that brings the car to rest is 175000N
Explanation:
The mass of the car, m = 1000 kg
Initial speed, u = 14 m/s
Final speed, v = 0 m/s (Since the car comes to a stop)
The time taken, t = 8 x 10^-2 s
The average force is calculated as:

The average force that brings the car to rest is 175000N
Answer:
28.5 m/s
Explanation:
The speed has two orthogonal components, horizontal and vertical. To decompose the speed into these components we can use these trigonometric equations:
Vh = V * cos(a)
Vv = V * sin(a)
The forwards velocity is the horizontal component, so we use
Vh = V * cos(a)
Vh = 50 * cos(55)
Vh = 50 * 0.57
Vh = 28.5 m/s
