Y=Y-0 +v-0*t-5t^2 solve for t (you will get a quadratic equation so use alphawolfram) I have only solved for stone one as for stone two they havent given much detail. then for final velocity average speed and average velocity seem more or less the same si...

speed = distance /time and time is 35+5=40.

I didn't get h but for f and g use the formula speed=distance/time and velocity=displacement/time. Time is the same as the one you got in c and d. for distance, the first stone is 24 but for the second stone, its 24+ the upward distance calculated by the...

divide the distance 320 by time 40seconds to get speed. for acceleration, divide this speed by 5.

The time to reach the highest point is tₒ= 2vₒ•sinα/2g =2•20•sin35/2•10 =1.15 s The time for covering the distance to the wall ‚d’ is t₁=d/vₒ•cosα =15/20•cos35= 0.92 s At horizontal distance d from the initial point the ball is at the height h₁=vₒ•sinα•t₁...

all i know is how to find acceleration. formula is (f - mu_1*m_b*g - mu_2*m_s*g)/m_b

THANK YOU FRANK!! <3

G is the same everywhere. Its the T that we need to input carefully.

My T is also 1.4. Someone asked me to divide that by 8.6x10^4.

My bob that approach got me a wrong answer. :(
