Motion in A Str...

A truck running along a straight line increases its speed uniformly from $$30$$m/s to $$60$$m/s over a time interval $$1$$ min. The distance travelled during this time interval is

If a body is thrown vertically upward and rises to a height of 10 m, then time taken by the body to reach the highest point is

A particle is thrown upwards from ground. It experiences a constant air resistance force which can produce a retardation of $$2 m/s^{2}.$$ The ratio of time of ascent to the time of descent is $$:\left[ g = 10\ m/s^{2} \right] $$

A particle moves in a straight line with a constant acceleration. It changes its velocity from $$ 10 ms^{-1} \ to \ 20 ms^{-1}$$ while passing through a distance $$135m$$ in $$t$$ second. The value of t is 

An object starting from rest travels 20 m in first 2 s and 160 m in next 4 s.
What will be the velocity( in $$m/s$$) after 7 s from the start.

A car starts from rest and moves along the x-axis with a constant acceleration $$5\ ms^{-2}$$ for $$8\ s$$. If it then continues with constant velocity, what distance will the car cover in 12 seconds since it started from rest?

A particle is projected vertically upwards with a speed $$u$$.

A stone is dropped from a certain height, which can reach the ground in 5 s. After 3 s of its fall, it is stopped and again allowed to fall. Then, the time taken by the stone to reach the ground for the remaining distance is :

A body falls from a height of 200 m. If gravitational attraction ceases after 2 s, further time taken by it to reach the ground is $$(g = 10  m  s^{-2})$$.

A body thrown vertically up with a velocity 'u' reaches the maximum height 'h' after 'T' second. The correct statement among the following is :
