As a stunt for movie two cars are to collide with each other head on. The two cars are initially 125 apart. Car A is heading straight for car B at 30 m/s and car B is at rest. Car A maintain the same velocity, while car B accelerates toward car A at constant 4 m/s2.
(a) Find out the time when do the car collide
(b) Where do the cards collides?
(c) How fast the car B moving at the moment of collision?

3.39724 seconds

23.0824792352 m, 101.917520765 m

13.58896 m/s

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

The equation of motion will be

The time at which the cars collide is 3.39724 seconds

Car B traveled 23.0824792352 m and Car A traveled 125-23.0824792352 = 101.917520765 m

The speed of car B is 13.58896 m/s

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
