Answer:
5.625 m/s²
Step-by-step explanation:
Intial velocity of car, u = 54 km/h = 54 × 5/18 m/s
u = 15 m/s
Car stops on applying brakes 20m
Displacement is covered by car ,S = 20m
finally car stops ∴ final velocity of car , v = 0
Now, use formula
V² = u² + 2aS , here a is Acceleration
⇒ 0 = (15)² + 2 × a × 20
⇒ -225 = 40a
⇒ a = -5.625 m/s² [ here negative sign shows that acceleration is opposite direction of motion of car ]
Hence, magnitude of acceleration = 5.625 m/s²
Answer:
B, D
Step-by-step explanation:
Any inequality that does not include the "or equal to" case will be graphed with a dashed line.
<h3>Application</h3>
The "or equal to" case is included when the inequality symbol is one of ≤ or ≥. When symbols > or < are used, the boundary line of the solution space is dashed (or the end point on the number line is an open circle).
The inequalities that will be graphed with a dashed line are ...
- 2x -4y < 12 . . . . choice B
- x +7 > -1 . . . . . . .choice D
625/1000 in simplest form=5/8 or 0.62500
