Answer:
<h2> v= 21.47m/s </h2>
Explanation:
For the car to turn at the about the centripetal force must not be greater than the static friction between the tires and the road
we will use the expression relating centripetal force and static friction below
let U represent the coefficient of static friction
Given that
U= 0.50
mass m= 1200-kg
radius r= 94.0 m
Assuming g= 9.81 m/s^2


substituting our given data in to expression we can solve for the speed V

making v the subject of formula we have

v= 21.47m/s
<em><u>hence the maximum velocity of the car is 21.47m/s</u></em>
Answer:
The height is 0.1014 m
Explanation:
Given that,
Mass = 0.0400 g
Charge 
Time t = 0.0420 s
Electric field 
We need to calculate the electric force on the particle
Using formula of electric force

Put the value into the formula


We need to calculate the gravitational force
Using formula of force

Put the value into the formula


We need to calculate the net force



We need to calculate the acceleration
Using newton's law




We need to calculate the height
Using equation of motion



Hence, The height is 0.1014 m
