Please Solve Q. D.2.... Answer given is Option (D)... Projectile Motion
D-2. A ball is horizontally projected with a speed v from the top of a plane inclined at an angle 450 with the
horizontal. How far from the point of projection Will the ball strike the Plane?
(B)
2v2
2üv2
(D)
D-3. A particle is projected at angle 370 with the incline plane in upward direction with speed 10 m/s. The angleof
incline plane is given 530. Then the maximum distance from the incline plane attained by the particle will be-
413m
(B) 4m
(C) 5m
(D) zero
DA. On an inclined plane of inclination 300, a ball is thrown at an angle of 600 with the horizontal from the foot of
the incline with velocity of 10 a ms-l. If g = 10 ms-2, then the time in which ball will hit the inclined plane
is -
(A) 1 sec.
(B) 6 sec.
(C) 2 sec.
(D) 4 sec.
1.
ASSERTION / REASONING
STATEMENT-I : In a projectile motion, the velocity at its highest point is zero.
STATEMENT-2 : In a projectile motion from ground to ground projection, the acceleration is g downwards due
to which speed of the projectile first decreases then increases to the same value.
IA) Statement-I is True, Statement-2 is True; Statement-2 is a correct explanation for Statement-I.
