Answer:

FALSE

Explanation:

As the ball is thrown in air

then the velocity of the ball has two components

v_x = v cos\theta

v_y = v sin\theta

now we also know that the acceleration due to gravity is vertically downwards  which is opposite in the direction of vertical velocity

So the acceleration due to gravity will decrease the vertical speed and the horizontal speed will remain constant

So here we can say that the vertical speed sill become minimum as soon as the ball will reach the highest point of its path

So the kinetic energy of the ball is minimum when ball will reach the highest point of its path

So the given statement is FALSE

F - False.

Its greatest kinetic energy is at the point of release.

It has the least kinetic energy, zero, at its highest point in its path.

A block of mass 8 m can move without friction
nekit [7.7K]

Answer:

Let M1 = 8 kg and M2 = 34 kg

F = M a = (M1 + M2) a

F = M2 g     the net force accelerating the system

M2 g = (M1 + M2) a

a = M2 / (M1 + M2) g = 34 / (42) g = .81 g = 7.9 m/s^2

Answer plz also give reason
user100 [1]

See this suggested solution.

1. Let a force F' is the vector sum of the forces P and Q, then it is shown on the attached picture and marked with red color.

2. according to the condition the force F holds the object, then F should have the same length as the force F' and the opposite direction.

3. using the conditions described in 2. the answer is C.
