As the car is in horizontal motion, so is be the ball. Now when the ball is thrown vertically upwards, it will have two forces acting on it i.e. the vertical force of throw and horizontal force of the balls inertia. Hence, the resultant force will be a projectile motion and the direction of motion...

What should be the fees for class XI and xii physics per class in Bhubaneswar?

According to me, the best fee will be the changed study pattern of the students from rote to conceptual and being able for themselves to choose what they actually want to do after 12th ( not necessarily engineering or MBBS). Thanks.

An elevator weighs 3000kg. What is its acceleration when the in the tension supporting cable is 33000N. Given that g = 9.8m/s2.
M = 3000 kg g = 9.8 m/s² T = 33000 a = ? Ma = Mg - T 3000 * a = 3000 * 9.8 - 33000 3000a = 29400 - 33000 3000a = - 3600 a = - 1.2 m/s².
