A baseball player hits a ball in such a way that it leaves bat with an initial speed of 40.0 m/s at 38.0 degrees. a. Find the horizontal and vertical components of the initial velocity.

b. What is the horizontal and vertical velocity of the ball at t=2.00 seconds.

c. What is the horizontal and vertical velocity of the ball at t=3.00 seconds.

d. What is the ball's motion at t=4.00s? (upward/downward)

e. How long did it take for the ball to reach maximum height?

f. Compute the ball's Maximum height.

g. How long will it take for the ball to finally hit the ground?

h. Find the ball's range.

Act has a 1200: 5 or 240: 1 turns ratio. it is short circuited. what is the maximum current at 1200a primary if we put a 100ohm resistor across the secondary end of the ct. use it as current source circuit.

Could someone . i have tried to solve myself but my calculation is off

Clothing made of several thin layers of fabric with trapped air in between, often called ski clothing, is commonly used in cold climates because it is light, fashionable, and a very effective thermal insulator. so it is no surprise that such clothing has largely replaced thickand heavy old-fashioned coats. (a) consider a jacket made of five layers of 0.1-mm-thick synthetic fabric (k = 0.13 w/m·°c) with 1.5-mm-thick air space (k = 0.026 w/m·°c) between the layers. assuming the inner surface temperature of the jacket to be 28°c and the surface area to be 1.25 m2, determine the rate of heat loss through the jacket when the temperature of the outdoors is 0°c and the heat transfer coefficient at the outer surface is 25 w/m2·°c. (b) what would your response be if the jacket is made of a single layer of 0.5-mm-thick synthetic fabric? what should be the thickness of a wool fabric (k = 0.035 w/m·°c) if the person is to achieve the same level of thermal comfort wearing a thick wool coat instead of a five-layer ski jacket?
