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

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

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 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
