Q2 of 101 Page 132

A block of mass 2.00 kg moving at a speed of 10.0 m/s accelerates at 3.00 m/s2 for 5.00 s. Compute its final kinetic energy.

Here let’s find the final velocity at the end of 5sec. Given initial velocity u = 10m/sec, acceleration a= 3m/, time t= 5sec

Therefore the final velocity is given by v = u+at So final K.E =
