1/15/20141 1. A car starts from rest and travel 10s with uniform acceleration 5m/s 2. Find out its final velocity. Here, u=0 m/s t=10s a= 5m/s 2 v=? We know,

1/15/20142 2.A car travels with uniform acceleration 5m/s 2 and after 10s its final velocity is 60m/s. What was its initial velocity? Here, v=60 m/s t=10s a= 5m/s 2 u=? We know,

1/15/20143 3.A car moving in uniform acceleration with initial velocity 10m/s and after 10s its final velocity is 60m/s. Find out its acceleration Here, u=10m/s t=10s v=60 m/s a= ? We know,

1/15/20144 4.A car travels with uniform acceleration 5m/s 2. Its initial velocity is 10m/s and final velocity is 60m/s. Find out the time it traveled. Here, a= 5m/s 2 u=10m/s v=60 m/s t=? We know,

1/15/20145 5.A car starts from rest and is accelerated uniformly at the rate of 5 m/s 2 for 10s. Find out the distance covered in meters. Here, a= 5m/s 2 t=10s u=0m/s x=? We know,

1/15/20146 6.A super sonic fighter dropped a bomb when it was 2 km above the ground. Find out the time needed for the bomb to reach ground. Here, a= 10 m/s 2 x= 2 km = 2000m u= 0m/s t = ? We know,

1/15/20147 7.A super sonic fighter dropped a bomb when it was 2 km above the ground. Find out the velocity of the bomb when it touches ground. Here, a= 10 m/s 2 x= 2 km = 2000m u= 0m/s v = ? We know,
