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 . 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 . 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 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 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 ball thrown vertically upward with a speed of 19.6ms^-1 from the top of a tower returns to earth in 6 sec. Find the height of tower.

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 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?

Rain is falling vertically with a speed of 30 m s^-1 . A woman rides a bicycle with a speed of 10 m s^-1 in the north to south direction. What is the direction in which she should hold her umbrella?

A constant force acting on a body of mass 3.0 kg changes its speed from 2.0 m s^-1 to 3.5 m s^-1 in 25 s. The direction of the motion of the body remains unchanged. What is the magnitude and direction of the force?

A cyclist is with a speed of8m/s. As he approaches a circular trun on road of radius 80m, he applies break and the speed is reduced at the rate of 0.5 m/s every second. What is the magnitude and direction of net acceleration of the cyclist on the turn?
