Abasketball player wishes to make a stunning last-second basket. with .8 seconds on the clock, she wants the ball to enter the hoop (height 3.05m) as time expires in the game. she shoots the ball with an initial speed of 7 m/s, from 2.1 meters above the ground.
1. at what angle (from the horizontal) does she shoot the ball?
2. draw qualitatively accurate position, velocity, and acceleration graphs for both dimensions of the ball's motion while it is in flight.

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
