Question

The motor connected to A (not$$ $$shown) is  pulling up the $$200$$ kg block along the rough incline with constant speed of $$5$$ $$m/s$$ when  power output of motor is $$10$$ kW. If the power  out put of motor is suddenly increased to $$15$$ kW  then the acceleration of block just after increasing the power is.

When the block is moving with constant velocity v then $$T=$$μ$$N+200g$$ $$sin$$ $$370TV$$ $$=$$ $$10$$ 	imes $${10^3}$$ &  & \mu N $$=$$ $$800NWhen$$  $$P1=15kW$$, then $$T1=15$$×$$1035=3000NT1-$$ μ$$N-200gsin370=200a$$⇒$$a=5m/s2$$

The motor connected to A (not shown) is pulling up the 200 kg block along the rough incline with constant speed of 5 m/s when power output of motor is 10 kW. If the power out put of motor is suddenly increased to 15 kW then the acceleration of block just after increasing the power is.
