    Hi! Im trying to solve a physic task, but cant get it right. Would really appreciate some help..

    To get help you must show some effort. Read the rules regarding homework help and follow the template (you have posted the question but need to list the relevant equations and your attempt at a solution).

    What he said. You said you can't get it right which implies you have at least had a go. Tell us what you did and we can help you find the error. This approach helps you learn and saves us having to repeat stuff you already know.
