A player throws a bail upwards with an initial speed of `29.4 m s^-1`.
What are the velocity and acceleration of the ball at the highest point of its motion?

A player throws a bail upwards with an initial speed of 29.4 m s^-1 . What is the direction of acceleration during the upward motion of the ball?

A player throws a bail upwards with an initial speed of 29.4 m s^-1 . Choose the x = 0 m and t = 0 s to be the location and time of the bail at its highest point, vertically downward direction to be the positive direction of x-axis, and give the signs of position, velocity and acceleration of the ball during its upward, and downward motion.

A player throws a bail upwards with an initial speed of 29.4 m s^-1 . To what height does the ball rise and after how long does the ball return to the player’s hands? (Take g = 9.8 m s-2 and. neglect air resistance).

A ball is thrown straight up. What is its velocity and acceleration at the top?

A boy standing on a stationary lift (open from above) throws a ball upwards with the maximum initial speed he can, equal to 49 m/s. How much time does the bail take to return to his hands? If the lift starts moving up with a uniform speed of 5 m/s and the boy again throws the ball up with the maximum speed he can, how long does the ball take to return to his hands?

A stone is thrown in a vertically upward direction with a velocity of 5 m s^1 . If the acceleration of the stone during its motion is 10m s^-2 in the downward direction, what will be the height attained by the stone and how much time will it take to reach there?

A ball is thrown vertically upwards with a velocity of 49 m/s. Calculate the total time it takes to return to the surface of the earth.

A man of mass 70 kg stands on a weighing scale in a lift which is moving (a) upwards with a uniform speed of 10 m s^1 (b) downwards with a uniform acceleration of 5 m s^2, upwards with a uniform acceleration of 5 m s-^1z. What would be the readings on the scale in each case? What would be the reading if the lift mechanism failed and it hurtled down freely under gravity?

If a body is moving in a circle of radius r with a constant speed v m/s. Its angular velocity is

A truck starts from rest and accelerates* uniformly at 2.0ms*2. At f = 10 s, a stone is dropped by a person standing on the top of the truck (6 m high from the ground). What are the (a) velocity, and (b) acceleration of the stone at f = 11 s? (Neglect air resistance:)
