Answer:
85 m/s
Explanation:
The formula for momentum is product of weight and velocity
p=mv where m is mass and v is velocity
Given that;
Momentum = 153 kg*m/s
Weight = 1.8 kg
Velocity = ?
p=mv
153 = 1.8 * v
153/1.8 = v
85 m/s
Answer:
⇒ 401.6 ± 7.1 ms
⇒ 57.2 ± 1.6 kg
⇒ 8.1 × 107 ± 2.9 × 105 m
⇒ 2.1 ± 8.8 µN
⇒ 294 ± 0.005 cm
Explanation:
As given all equation we do without calculation we will get here round these calculations which is given below as
a) 401.6473 ± 7.0912 ms
⇒ 401.6 ± 7.1 ms
b) 57.212 ± 1.612 kg
⇒ 57.2 ± 1.6 kg
c) 8.12754×107 ± 2.847×105 m
⇒ 8.1 × 107 ± 2.9 × 105 m
d) 2.94 ± 8.803 µN
⇒ 2.1 ± 8.8 µN
e) 294 ± 0.00481 cm
⇒ 294 ± 0.005 cm
Answer: 40.4M/s
Solution: 46.6/1.15 = 40.4347826 then round it to a single decimal point, since 3 is lower than 5 it will be rounded to 40.4
Answer:
D
Explanation:
Look at the two of them, if you put them together the image is identical to that of the unknown sample.
For this use the formula:
d = Vo * t - (at^2) / 2
Clearing t:
t = d/(v + 0.5*a)
Replacing:
t = 5 m / (7.2 m/s + 0.5 * (-1.1 m/s²)
Resolving:
t = 5 m / (7.2 m/s + (-0.55 m/s²)
t = 5 m / 6.65 m/s
t = 0.75 s
Result:
The time will be <u>0.75 seconds.</u>
