Closer than the outer planets, inside the Asteroid Belt between Mars and Jupiter.
Answer:
v = 87.57 m/s
Explanation:
Given,
The initial velocity of the car, u = 0
The final velocity of the car, v = 60 mi/hr
The time period of car, t = 8 s
= 0.00222 hr
The acceleration of the car is given by the formula,
a = (v -u) / t
= 60 / 0.00222
= 27027 mi/hr²
If the car has initial velocity, u = 50 mi/hr
The time period of the car, t = 5.0 s
= 0.00139 hr
Using first equations of motion
<em> v = u + at</em>
= 50 + (0.00139 x 27027)
= 87.57 mi/hr
Hence, the final velocity of the car, v = 87.57 mi/hr
Answer:
F =1490.9 N
Explanation:
given,
work done = 82 J
compression length = 0.220 m
for parallel combination
= 2 k
work done
force =
F = kx
F = 3388.43 ×0.22
F =745.45 N
the additional work done
final potential energy = 
= 4 W = 328 J
the additional work = 328 - 82 = 255 J
maximum force
F = k × 2x
F = 2×745.45
F =1490.9 N
Well he could remove the drawers to make it lighter, which causes less friction
