## Britches.Slayer one year ago hi!!! do you know some hard kinematics (with uniform and varying acceleration) and projectile motion problems? :((( I need those questions so I can review!! :((

• This Question is Open
1. Mashy

How hard are we talking about? ;-)

2. Mashy

*) A projectile is projected upwards with a blistering speed of 5km/s. If the earth has a radius of 6400 km, calculate how high about the earth's surface does the projectile reach (neglect the rotation of the earth and consider earth to be a perfect sphere )

3. Mashy

2) A man stands at the bottom of an incline (alpha). He throws a projectile with an angle beta with respect to the incline. If you consider the man to be at origin. Find the co ordinates at which the projectile hits the incline|dw:1409406103623:dw|

4. Mashy

then speed of projection as u or something :P

5. Mashy

take*

3) Two objects are throw upwards.. one with 50m/s and another with 60m/s 5 seconds later. Find when and where will the two objects meet?

7. Mashy

4) An object is moving in 3 dimensions with position vector function \[r(t) = (2t^3 - 4)i + (t^2 - 2t + 5) j - (3t^2)k (m)\] Find the magnitude of average acceleration and also the angle it makes with the yz plane.. from t =2s to t = 5s. i, j, k are unit vectors along the positive x, y, and z axes respectively

8. Mashy

Tell me if u want harder ones.. ll refer some books..
