Answer:
238
Step-by-step explanation:
the top and bottom are going to be, 7 x 7 aka 49.
all the sides will be, 7 x 5 aka 35.
49 + 49 + 35 + 35 + 35 + 35 = 238
1. F=ma
F = (2500)(4.8)
F = 12,000 N
2. a = F/m
a = 250/40
a = 6.25m/s^2
3. m = F/a
m = 50/1.2
m ≈ 41.67 kg
4. Speed = Distance covered/time
= 2300/4.25*
≈ 541.18 mph
*15 minutes is 0.25 hours (15 times 4 = 60)
5. same formula above
250/45 ≈ 5.56 km/min
remember these formula triangles for the future :)
The value of expression is 41
I think the answer is
No
No
Yes
But I'm not sure about the last one
