Answer:
Before start of slide velocity will be 14.81 m/sec
Explanation:
We have given coefficient of static friction 
Angle of inclination is equal to 
Radius is given r = 28 m
Acceleration due to gravity 
We know that 
So before start of slide velocity will be 14.81 m/sec
Can we see the diagram? Thanks.
Velocity
Because velocity is speed with direction. In this scenario, the speed has not changed, but the direction did.
Answer:
a = -8.912 m/s²
Explanation:
Given,
The initial velocity of the car, u = 28 m/s
The final velocity of the car, v = 0
The distance traveled by car, d = 88 m
The velocity displacement relation is given by the formula
v = d/t
∴ t = d/v
Substituting in the above values in the given equation
t = 88/28
= 3.142 s
The acceleration is given by the formula
a = (v-u)/t
= (0 - 28)/3.142
= -8.912 m/s²
The negative sign is that the car is decelerating.
Hence, acceleration a = -8.912 m/s²
The artic tundra can be found in D. All of the above.
