+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.
Can we solve this using equation of trajectory
general question related to problem: does a particle in projectile along plane attains the same speed twice ?
integer answer??
did anyone get this??
yeah it would if the path is symmetrical ig
but if the plane is inclined it should not
what is the answer?
Taking it from f.o.r. of box, effective gravity is gcos(53)=3, now (either by trajectory equation or by equation of motions), you get alpha=5
yeah getting the same
u can try using relative motion
along the incline
when the ball enters the box both are performing relative motion...find out the time when height of ball becomes 2m(its coming out 2 and 1/3) using 2nd eqn of motion and then use distance=v(rel) * t.. since relative acc is zero along incline for both.... t will be 2-1/3
o just saw that ur doubt was something else
d = 7*5/root3 right ??
yup alpha is 5
yep
