Best ResponseYou've already chosen the best response.0impulse roughly can be said as change in momentum. That is a hint.

Best ResponseYou've already chosen the best response.0yeah the magnetic field is it out of the paper? its zero into the paper or at the bottom of paper?

Best ResponseYou've already chosen the best response.0You got to revise your right hand thumb rule to understand that, for same direction, magnetic fields cancel in between.

Best ResponseYou've already chosen the best response.0The coefficient of static friction between car’s tires and a level road is 0.80. If the car is to be stopped in a maximum time of 3.0 s, its maximum speed is (a) 2.4 m/s (b) 23.5 m/s (c) 7.8 m/s (d) 2.6 m/s whch equation will be applied here?

Best ResponseYou've already chosen the best response.0. A monkey of mass 20kg rides on a 40kg trolley moving with constant speed of 8 ms 1 along a horizontal track. Frictional forces can be neglected. If the monkey jumps vertically with respect to the moving trolley to grab the overhanging branch of a tree, the speed of the trolley after the monkey has jumped off is
