Question

Good evening
Please help
an object is thrown vertically upwards with an initial velocity of 60 metre per second. calculate the velocity of the object when it is halfway up.​

Answer 1

Answer:

Given v = 20 ms^-1

KE= 1\2mv^2

=1\2*m*400

=400*m

at H=h

PE= 1\2 KE

mgh=1/2*200*m

mgh=100*m

gh=100

h=100/g=100/9.8

h=10.20metres
