a) The car’s speed just after leaving the icy portion of the road is the first part
We have s = ut +
Here s = 130 m, a = -1.2
, u = 76 mile/hr = 33.975 m/s

After 14.72 seconds cars speed is given by v =u +at
u = 33.975m/s, a = -1.2 
v = 33.975-1.2*14.72 = 16.31 m/s
So velocity of car on leaving icy surface = 16.31 m/s
b) Time taken after icy surface
0 = 16.31 - 7.10*t
t = 2.23 seconds
Distance traveled during this time

Total distance traveled = 130+18.74 = 148.74 m
c) Total time taken = 14.72+2.23=16.95 seconds
Answer:
128.8m/s
Explanation:
74 × 60 = 4440 convert minutes to seconds
572000/4440 = 128.82882... speed=distance/time
Answer:
<h3>The answer is 4 N</h3>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 2 × 2
We have the final answer as
<h3>4 N</h3>
Hope this helps you
Answer:
a = v^2 / R = 4.5^2 / R = 29
R = 4.5^2 / 29 = .70 m
