Embibe Experts Solutions for Exercise 4: EXERCISE

A ball is projected from the foot of an incline plane of inclination $30°,$ at an angle $60°$ with the horizontal with velocity $20\sqrt{3} \mathrm{m} {\mathrm{s}}^{-1}.$ The time after which the ball will strike the plane is

Path of a projectile as seen from another projectile is a

A particle is projected on an incline plane having inclination $30°,$ at an angle $30°$ with the incline plane with a velocity $15 \mathrm{m} {\mathrm{s}}^{-1}.$ Range of the projectile on the incline plane will be

For a projectile thrown up an incline plane (making an angle $\theta$ with horizontal), maximum range on the incline can be achieved by projecting at an angle _____$°+\frac{\theta }{2}$ from the horizontal ( $\theta$ is acute).

For a projectile thrown at an angle $\theta$ with the horizontal ground, maximum range on the ground can be achieved by projecting at $\theta =$_____$°$. (In degrees)

If angle of incline is $37°$ from horizontal and body is projected up at $53°$ from the incline then range will be.

A ball is projected from point $A$with velocity $10 \mathrm{m} {\mathrm{s}}^{-1}$perpendicular to the inclined plane as shown in the figure. Range of the ball on the inclined plane is

On an inclined plane inclined at an angle of $30°$ to the horizontal, a ball is thrown upwards with a velocity of $10 \mathrm{m} {\mathrm{s}}^{-1},$ at an angle of $60°$ to the inclined plane. Its range on the inclined plane is
