Hi freinds! How you are doing, hope great? Check out this questions, about 60% of students that attempted it got it wrong. So try and see if you can do justice required of them. Happy solving!
1. A body of mass 20kg, moving with uniform acceleration has an initial momentum of 200kgm/s after 10s, the momentum is 300kgm/s. What is the acceleration of the body?
2. Two bodies P and Q are projected on the same horizontal plane, with the same initial speed but a different angles of 30o and 60o respectively to the horizontal, neglecting air resistance, what is the ratio of the range of P to that of Q?
no1 ans is 0.5...while no2 and is 1:√3...thanks
