19.A car initially at rest starts with a uniform acceleration and gains a velocity of 20m/s in 4s.The displacement of the car is
solution: a car initially starts at rest (u)=0 it is moving with uniform acceleration and the car gains velocity(v)=20m/s. the time taken by the car is (t)=4s we have the formula v=u+ at 20=0+4a 20=4a a=5m/s2 we got the uniform acceleration a =5m/s2 then ,for displacement S=ut+1/2at2 =0*4+1/2*5*4*4 =1/2*5*2*4 =40m or displacement=(u+v)/2*t =(0+20)/2*4 =40m The …
18.A passenger in moving train tosses the coin, why did the coin falls behind the passenger?
answer: if a passenger tosses the coin, the coin will go up and it has only gravitational acceleration. but train moves with uniform acceleration towards. so, the coin will fall behind the passenger.
