A projectile is fired at 60^(@) with horizontal as shown It is observed from a frame accelerated along +x at (g)/(sqrt(3)) .The shape of the path observed is qquad y

Why does a projectile fired along the horizontal not follow a straight line path ?

A projectile is fired from horizontal at an angle theta . What are the horizontal and vertical acceleration at the highest point ?

Imagine a smooth tunnel along a chord of nonrotating earth at a distance (R)/(2) from the centre. R is the radius of the earth. A projectile is fired along the tunnel from the centre of the tunnel at a speed V_(@)=sqrt(gR) [g is acceleration due to gravity at the surface of the earth]. (a) Is the angular momentum [about the centre of the earth] of the projectile onserved as it moves along the tunnel? (b) Calculate the maximum distance of the projectile from the centre of the earth during its course of motion.

From the ground, a projectile is fired at an angle of 60 degree to the horizontal with a speed of 20" m s"^(-1) The horizontal range of the projectile is

A projectile is launched with a speed of an angle 60^@ with the horizontal from a sloping surface of inclination 30^@ . The range R is: (g=10m//s^2)

From the top of a hill 480 m high , a projectile is fired horizontally with a speed of 96 m//s . Calculate (i) the time taken by projectile to reach the ground . (ii) the distance of the target from the hill . (iii) the velocity with which the projectile hits the ground . Take g=10ms^(-2)

A constatnt force of 10 N act on a block as shown in figure intal velocity of the particle is zero. It is observed from three frames of reference S_(1),S_(2) and ground. The frame S_(1) start from rest and move with constnat acceleration 10m//s. The frames S_(1)and S_(2) and particle start moving simultaneously at t=0. Work done on block in 1 s as observed from frame S_(1) is
