A football is kicked with a speed of `22(m)/(s)` at an angle of `60^@` to the positive x direction taken along horizontal. At that instant, an observer moves past the football in a car that moves with a constant speed of `11(m)/(s)` is the positive x direction. Take `+ve` y direction vertically upwards. `(g=10(m)/(s^2)`)

A football is kicked at a speed of 20 m//s a projection angle of 45^(@) . A receiver on the goal line 25 metres away in the direction to the kink runs the same instant to meet the ball. Befrom it hits the ground?

A shell is fixed from a cannon with a speed of 100 m//s at an angle 60^(@) with the horizontal (positive x-direction). At the highest point of its trajectory, the shell explodes into two equal fragments. One of the fragments moves along the negative x-direction with a speed of 50 m//s . What is the speed of the other fragment at the time of explosion.

On an object of mass 1 kg moving along x-axis with constant speed 8 m/s, a constant force 2 N is applied in positive y-direction. Find its speed after 4 seconds.

On an object of mass 1 kg moving along x-axis with constant speed 8 m/s, a constant force 2 N is applied in positive y-direction. Find its speed after 4 seconds.

A football ils kicked with a velocity of 20 m/s at an angle of 45^0 wilth the horizontal. A. Find the time taken by the ball to strike the ground. b.Find the maximum height it reaches. C. How far away from the kick dows it hit the ground? Take g=10 m/s^2 .

A man moving with 5 m/s observes rain falling vertically at the rate of 10 m/s find the speed and direction of the rain with respect to ground .

A projectile is thrown with a velocity of 20 m//s, at an angle of 60^(@) with the horizontal. After how much time the velocity vector will make an angle of 45^(@) with the horizontal (in upward direction) is (take g= 10m//s^(2))-
