Question

When a man started from rest with constant acceleration along an incline plane of angle $3 7^{\circ}$ , from horizontal he found rain to be falling vertically. After t seconds, he finds rain to strike him horizontally. Assume that actual velocity of rain is constant with magnitude $4 m / s$ . Choose the correct option(s) :

Options:

Answer:

C

Solution:

$- 4 + \frac{3}{5} a t = 0 \Rightarrow a t = \frac{20}{3}$

The man must move down the incline. So, for $a = 1$ , $t = \frac{20}{3}$ sec.

− 4 + 5 3 ​ a t = 0 ⇒ a t = 3 20 ​ The man must move down the incline. So, for a = 1 , t = 3 20 ​ sec.
