Question

Hall stones falling vertically with a speed of 12.13 m/s hits the wind screen which makes an angle so
with the norizontal. If car is running at velocity v (in m/s) so that the driver find the nailstones sing
perpendicular to the wind screen. Find the value of ?
(1) 6 m/s
(2) 8 m/s
(3) 5 m/s
(4) 9 m/s​

Answer 1

Answer:

Answer:

Explanation:

=> Hey,

=> If you want to find the velocity of the car if the driver finds the hailstones rebound vertically after striking, then the solution of your query is here:

=> The velocity of a hailstone relatively car = V.

V = V_C + V_HV=V

C

+V

H

where,

V_CV

C

= the velocity of car relatively ground,

V_HV

H

= the velocity of a hailstone relatively ground.

=> velocity of the car :

V_C = V_HcotV

C

=V

H

cot 30° [cot 30° = √3]

= 12√3*√3 m/s

= 12 * 3 m/s

= 36 m/s.

The velocity of the car if the driver finds the hailstones rebound vertically after striking is 36 m/s
