I don't have any take-off speed. The height i guess would be 0.28, the range could be the distance (0.086) ?

Hi! I am trying to solve a physics task, but can't get it right. Would really appreciate some help.. A disk of uniform thickness has a radius of 2cm and the mass of 2kg. How large torque is needed to accelerate it from the rest up to 60 rad/s in 6seconds?

I read in a physicbook that the maximum distance of movement of an object in 2 dimensions, irrespective of wind resistance, the angle will always be equal to 45 (as evidenced by sin2 * 45 = 1)

could be, yes. my teacher don´t speak english, so he translates all the tasks in google translate ... Honestly, i have no clue what he is asking for. So, i don't know, i don't know i don't know, and i am sorry for not answering your questions. I just need a suggestion

Task 2: Calculate the acceleration and maximum range of a jump in the case of a frog. The maximum vertical hight is 0.28m and the distance of acceleration is 0.086m. The gravity constant g=9.81 m/s^2 This is the task i got (word for word), nothing less nothing more

I don't have any more info, so I don´t know

How do you calculate the acceleration and the maximum range of a jump (in this case a frog,) when the maximum vertical hight is 0.28m and the distance of acceleration is 0.086 m? I also tried to use the 45 degree, and the gravitation constant 9,81 m/s^2 but can't get it right..
