Question

'You toss a marble straight up into the air with a speed of 1.3 meters per second. How long does it take the marble to reach its highest point?'

Answer 1

think about the movement of the marble and draw a picture

Answer 2

we know that a= -9.8 m/s^2. we know initial velocity is 1.3 m/s. when it reaches its highest point, we know final velocity is 0. so what would be the height? use this equation: (final velocity)^2 = (initial velocity)^2 + 2(acceleration)(height) and then solve for the height!

Answer 3

Required equation is
v=u-gt

Answer 4

U know at highest point
The velocity v=0

Answer 5

u=initial velocity

Answer 6

g=gravitational acceleration

Answer 7

Time=t=?
