Question

A Basketball player tosses a ball at a speed of 45.0 m/s at an angle of 40 Degrees in relation to the ground. It happens to land on the court some distance from the starting point.\

C) What are the horizontal & vertical components of the balls acceleration when it reaches its max height

D) Is there a point on the trajectory where the velocity and acceleration of the ball are perpendicular to each other, is so where ?

Answer 1

Solni Given; uz 45mls 0 = 40 u= 45m/s Ilmax © At maximum height, Hmax, there is only vertical component of aceleration and no component of Horizontal aceleration. dy=g = 9.81 m/s2 (downwards) _Range An = 0 Also during the whole trajectory /Path only vertical component of acceleration is present, the object moues horizontally with constant velocity = Ucoso ☺ yes Uy=0 leeuwse ayang At maximum Height, velocity and Queleration are perpendicular to each other werey , Us Ucoso= 34.47 mis aya g = 9.81m|s2
