Question

SOLVE THIS QUESTION ...........NO SPAMS OTHERWISE U KNOW VERY WELL WHAT WILL HAPPEN ​

Answer 1

Answer:

d)zero

Explanation:

• horizontal velocity remains constant throughout the motion which is given by u cosx

(where,x is the angle made with horizontal)

• vertical velocity changes every instant and is given by u sinx
• at the highest point, there is no vertical component of velocity and velocity will be provided by the horizontal component only (i.e, u cosx)

________________________________

for ball 1:

• x= 90° (because, the ball is thrown vertically)
• hence, velocity at the top most point , u cosx= ucos90= u×0=0
• kinetic energy at the highest point ,

$k = \frac{1}{2} m {v}^{2} \\ = \frac{1}{2} m {vcosx}^{2} \\ = \frac{1}{2} m \times {0}^{2} = 0$
