A player throws a ball upwards with an initial speed of `29.4 ms^(-1).` What are the velcity and acceleration of the hall at the highest point os its motion ?

A player throwsa a ball upwards with an initial speed of 29.4 ms^(-1) . (i) What is the direction of acceleration during the upwared motion of the ball? (ii) What are the velocity and acceleration of the ball at the highest point of its motion? (iii) Choose the x=0 and t=0 to be the location and time of the ball at its highest point, vertically downward direction to be the positive direction of X-axis, and give the signs of positive, velocity and acceleration of the ball during its upward, and downward motion. (iv) To what height does the ball rise and after how long does the ball return to the player's hand?( Take g =9.8 ms^(-2) , and neglect air resistance).

A player throws a ball upwards with an initail speed of 129.4 ms^(-1) (a) What is the direction of acceleration during the upward motion of the ball ? (b) What are the velocity and accleration of the ball at the ighest point os its motion. ( c) Choose the =x 0 aand t= 0 be the loction and time at its highest point, vertically downward direction to be the positve direction of X-axis and give the signe of position, velocity and accelration of the ball during its upward, and downward motion. (d) To what hight does the ball rise and after how long does the ball returns to the plausr s hands. (Take g= 9.8 ms^(-23) and begleact air resistance)

A ball is thrown in air . What are its velocity and acceleration at the highest point ?

A ball is thrown upwards with a velocity of 29.4 ms^(-1) in the absence of air resistance. (i) Mention the direction of the acceleration during the upward motion of the ball. (ii) What are the velocity and acceleration of the ball at the highest point? (iii) How much high the ball goes up? (iv) Find the time taken by the ball to reach the ground. Take g = 9.8 ms^(-2)

A player throws a ball upwards with an initial speed of 30 m s^(-1) . How long does the ball take to return to the player's hands? ( Take g = 10 m s^(-2) )

In case of a projectile motion, what is the angle between the velocity and acceleration at the highest point?
