    We need not calculate magnitude of impulse here, one experiencing larger impulse will rise higher.

    impulse roughly can be said as change in momentum. That is a hint.

    If a balls has risen higher, it means it must have greater initial velocity at the bottom ?

    yeah the magnetic field is it out of the paper? its zero into the paper or at the bottom of paper?

    You got to revise your right hand thumb rule to understand that, for same direction, magnetic fields cancel in between.

    The 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?

    . A monkey of mass 20-kg rides on a 40-kg 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
