Questions
A particle is projected on to an incline plane of inclination 300 as shown in fig. (g=10m/) then:
a
the time of flight of the projectile along the inclined plane is 1.63s
b
the time of flight of the projectile along the inclined plane is 3s
c
the time of flight of the projectile along the inclined plane is 6.31s
d
the time of flight of the projectile along the inclined plane is 5s
detailed solution
Correct option is A
time of flight=T=2usinα−βgcosβ T=(2)(202)sin(450−300)(10)cos300 T=402sin 1510×32=40×1.414×0.255×1.732=1.63secTalk to our academic expert!
