Q>At a speed of 60km/h U r driving a car in N direction suddenly u take a turn towards E direction at 73km/h.
What is height of driver?
Wats d ans?
To find the height of the driver, we need additional information such as the angle of the turn or the time it takes to make the turn. The given information about the speed and direction of the car is not sufficient to determine the height of the driver.
However, if we assume that the turn is a right angle turn, we can use the concept of centripetal acceleration to estimate the height of the driver.
Centripetal acceleration is given by the formula: a = v^2 / r, where 'a' is the centripetal acceleration, 'v' is the velocity of the car, and 'r' is the radius of the turn.
In this case, the initial velocity (v1) is 60 km/h towards the N direction, and the final velocity (v2) is 73 km/h towards the E direction. Assuming the turn is a right angle turn, the change in velocity is equal to the initial velocity (v1) since the final velocity (v2) is perpendicular.
To find the change in velocity, we can convert the velocities from km/h to m/s by dividing them by 3.6. We get v1 = 60/3.6 = 16.67 m/s and v2 = 73/3.6 = 20.28 m/s.
Now, we can calculate the change in velocity (Δv) as follows:
Δv = v2 - v1
Δv = 20.28 - 16.67
Δv ≈ 3.61 m/s
Assuming the turn is made in a very short time interval, we can treat it as an instantaneous turn and calculate the radius of the turn (r) using the formula for centripetal acceleration (a):
a = (Δv)^2 / r
Rearranging the formula to solve for radius (r), we get:
r = (Δv)^2 / a
The value of centripetal acceleration (a) depends on the specific turn made and would require additional information or assumptions.
Without information about the turn or its radius, we cannot accurately calculate the height of the driver.
