A ball is thrown upwards with a velcoity of ` 80 m//s` at an angle of ` 30^@` to the horizontal . Find its velcituy after one second.

A body is thrown with a velocity of 9.8 m//s making an angle of 30^(@) with the horizontal. It will hit the ground after a time

A body is thrown with a velocity of 9.8 m//s making an angle of 30^(@) with the horizontal. It will hit the ground after a time

A body is thrown with a velocity of 9.8 m/s making an angle of 30^(@) with the horizontal. It will hit the ground after a time

A projectile is thrown with a velocity of 20 m//s, at an angle of 60^(@) with the horizontal. After how much time the velocity vector will make an angle of 45^(@) with the horizontal (in upward direction) is (take g= 10m//s^(2))-

A projectile is thrown with a velocity of 20 m//s, at an angle of 60^(@) with the horizontal. After how much time the velocity vector will make an angle of 45^(@) with the horizontal (in upward direction) is (take g= 10m//s^(2))-

A ball is thrown upwards during its upward motion

A cannon ball is thrown with an initial velocity of 40m/s at an angle of 53^(@) above the horizontal from ground.After some time,the ball is seen to travel at an angle of 37^(@) below horizontal.Find the time elapsed (in second) till then.
