Answer:
the correct answer is option C
Answer:
v = 66 m/s
Explanation:
Given that,
The initial velocity of a car, u = 0
Acceleration of the car, a = 11 m/s²
We need to find the final velocity of the toy after 6 seconds.
Let v is the final velocity. It can be calculated using first equation of motion. It is given by :
v = u +at
v = 0 + 11 m/s² × 6 s
v = 66 m/s
So, the final velocity of the car is 66 m/s.
Limestone, Sandstone, and Shale would be the answer.
<h2>
Speed of jet is 730 miles per hour and speed of wind is 160 miles per hour.</h2>
Explanation:
Let the speed of jet be j and speed of wind be w.
Flying against the wind a jet travels 1710 miles in 3 hours
Distance = 1710 miles
Time = 3 hours
We have
Distance = Speed x Time
1710 = Speed x 3
j - w = 570 miles per hour ----------------eqn 1
Flying with the wind the same jet travels 6230 miles in 7 hours
Distance = 6230 miles
Time = 7 hours
We have
Distance = Speed x Time
6230 = Speed x 7
j + w = 890 miles per hour ----------------eqn 2
eqn 1 + eqn 2
2 j = 1460
j = 730 mph
Substituting in eqn 2
730 + w = 890
w = 160 mph
Speed of jet is 730 miles per hour and speed of wind is 160 miles per hour.
1 km = 1000 m
1 min = 60 s
Entonces
60 km/min * (1000 m/km) * (1/60 min/s) = 1000 m/s
