As a protest against the umpire's calls, a baseball pitcher throws a ball straight up into the air at a speed of 19.5 m/s. In the process, he moves his hand through a distance of 1.40 m. If the ball has a mass of 0.150 kg, find the force he exerts on the ball to give it this upward speed.

As a protest against the umpire's calls, a baseball pitcher throws a ball straight up into the air at a speed of 18.0 m/s. In the process, he moves his hand through a distance of 1.40 m. If the ball has a mass of 0.150 kg, find the force he exerts on the ball to give it this upward speed.

Starting from rest, a 64.0 kg woman jumps down to the floor from a height of 0.800 m, and immediately jumps back up into the air. While she is in contact with the ground during the time interval 0 < t < 0.800 s, the force she exerts on the floor can be modeled using the function F = 9,200t − 11,500t2 where F is in newtons and t is in seconds.   (c) With what speed (in m/s) did she leave it? (Round your answer to at least three significant figures.) (d) To what height (in m) did she jump upon leaving the floor?

(2.2 m/s)î + (-7.8 m/s)j. Two of the forces are F = (1.5 N)i + (3.8 N)i + (-2.0 N) an Three forces act on a particle that moves with unchanging velocity v = F:= (-4,6 N)i + (3.8 N); + (-22 N)ê. What is the third force?

Can you please help me with this question please? Thank you so much!

A flea jumps by exerting a force of Flea = -1.52 x 10-5 ĵ N straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of = ( 10-5 î + 2.44 × 10¬5 k) N on the flea. Find the acceleration of the flea if its mass is 6.00 x 10-/ kg. Express your answer in vector form. Assume that the +x axis is to the Fwind -4.64 right, the +y axis is up along the page, and the +z axis is out of the screen towards you as shown in the figure below. -77.33i – 25.33j + 40.66k a =

Determine the force Q-> when the block moves with constant velocity. Express your answer in vector form.

Under the influence of its drive force, a snowmobile is moving at a constant velocity along a horizontal patch of snow. When the drive force is shut off, the snowmobile coasts to a halt. The snowmobile and its rider have a mass of 139 kg. Under the influence of a drive force of 180 N, it is moving at a constant velocity whose magnitude is 5.43 m/s. The drive force is then shut off. Find (a) the distance in which the snowmobile coasts to a halt and (b) the time required to do so. (a) S = (b) t = i i

A 0.697 kg football is thrown upward with an initial speed of 49.7 m/s.  Neglecting wind resistance, what is the force on the ball when it reaches half its maximum height? Use g=9.8 m/s

As a protest against the umpire's calls, a baseball pitcher throws a ball straight up into the air at a speed of 22.0 m/s. In the process, he moves his hand through a distance of 1.20 m. If the ball has a mass of 0.150 kg, find the force he exerts on the ball to give it this upward speed.
