A tennis player tosses a tennis ball straight up and then catches it after 1.63 s at the same height as the point of release. (a) What is the acceleration of the ball while it is in flight? magnitude direction Select m/s² (b) What is the velocity of the ball when it reaches its maximum height? magnitude m/s direction --Select- (c) Find the initial velocity of the ball. m/s upward (d) Find the maximum height it reaches.
From the top of a building, you throw a ball upward with initial velocity of 4.00 m/s at an angle of 50 degrees with respect to the horizontal. a) what are the velocity components of the ball at point A, B, C, and D? b) how far from the building is point D? From the top of a building, you throw a ball upwards with initial velocity of 4.00 m/s at an angle of 50° with respect to the horizontal....
You throw a ball straight up into the air. At the top of its trajectory just before it begins to fall, its velocity and magnitude of acceleration are: Select one: O a velocity is 9.8 m/s, acceleration is zero O b. velocity is 9.8 m/s, acceleration is 9.8 m/s2 O c. velocity is zero, acceleration is zero O d. velocity is zero, acceleration is 9.8 m/s2
You throw a ball straight up from the ground (? = 0) with an initial speed of 20 m/s. At the same time (? = 0), another ball is dropped from a building that is 15 m high. How long will it take for the two balls to be exactly the same height off the ground?
2) You throw a ball straight up with an initial velocity 15.0 m/s a) How high does it go? Ignor e the air resistance. (1 mark) b) How long does it take for the ball to reach its maximum height? (1 mark) What is the ball velocity when the ball is 6.00 m above the initial throwing point? c) (1 mark) What is the velocity of the ball when it back to initial point? (1 mark) d) 2) You throw...
A tennis player tosses a tennis ball straight up and then catches it after 2.00 s at the same height as the point of release. (a) What is the acceleration of the ball while it is in flight? (b) What is the velocity of the ball when it reaches its maximum height? Find (c) the initial velocity of the ball and (d) the maximum height it reaches.
A player hits a tennis ball close to the ground with an initial velocity of 32 m/s at an angle 35˚ from the horizontal. Assume air resistance is negligible. a) If the opponent doesn't hit the ball, how long will the ball be in the air? b) What is the ball's velocity at the highest point in its trajectory? c) How high will the ball go? Please show all work and steps
Two throw A blue ball is thrown upward with an initial speed of 22.2 m/s, from a height of 0.8 meters above the ground. 2.7 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 9.2 m/s from a height of 27.8 meters above the ground. The force of grandly due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s^2. What is the speed of...
13. What initial velocity would you have to throw a 620g tennis ball for it to reach a max height of 14m (hint: V=0 at max height)? 14. Find the force acting on a 2500kg car that experiences a change in momentum, Ap, of 60 kg*m/s over a period of 8 seconds.
You throw a ball vertically up into the air with a velocity of 5 m/s. What is its acceleration just as it leaves your hand? What is its velocity when it reaches its maximum height? What is its acceleration when it reaches its maximum height?
