Answer:
According to the Question
Firstly we calculate the initial velocity of the car . Using 1st equation of motion
v = u + at
where,
v is the final velocity
a is the acceleration
u is the initial velocity
t is the time taken
Substitute the value we get
:\implies:⟹ 0 = u + (-10) × 5
:\implies:⟹ -u = -50m/s
:\implies:⟹ u = 50m/s
So the initial velocity of the car is 50m/s
Now, calculating the final velocity of the car by using 3rd equation of motion.
v² = u² + 2as
substitute the value we get
:\implies:⟹ 0² = 50² + 2(-10)× s
:\implies:⟹ 0 = 2500 -20s
:\implies:⟹ -2500 = -20s
:\implies:⟹ 20s = 2500
:\implies:⟹ s = 2500/20
:\implies:⟹ s = 125 m
Hence, the distance covered by the car before coming to rest is 125 metres.
