my Voy=4.9, my V=8.5 so i did -5.73=-12.1+9.8t, 6.37=9.8t, =0.65 SO then i used the 3rd equation so yea its 1.2m

nvm i got 8.5 for the first one, but if it isn't that then it is 1.2 it depends which i was supposed to use for the firs component which I am still confused about

ok for the first problem was ur max height 4.9 m. and for problem two did u get 7 m/s as the horizontal component of the initial point? u don't have to tell me the answer if its wrong, jus tell me if its wrong because i think i put a negaive where i shouldn't have

A child kicks a ball with an initial velocity of 8.5 meters per second at an angle of 35° with the horizontal, as shown. The ball has an initial vertical velocity of 4.9 meters per second and a total time of flight of 1.0 second. [Neglect air resistance.] what is the max height? what is the...

A man stands on the roof of a 17.0 m tall building and throws a rock with a velocity of magnitude 24.0 m/s at an angle of 33.0° above the horizontal. You can ignore air resistance. (a) Calculate the maximum height above the roof reached by the rock. (b) Calculate the magnitude of the...

Ok I think i am getting the hang of this stuff. But, A rookie quaterback throws a football with an initial upward velocity component of 16.0 m/s and a horizontal velocity component of 19.0 m/s. Ignore air resistance. a. how much time is required for the ball to reach the highes point of...

but for the 2nd part, wouldn't i use the vertical direction equation x=(Vo)(t)?

actually 3.58 s is the time

A projectile is fired horizontally from a gun that is 63.0 m above flat ground. The muzzle velocity is 250 m/s. (a) How long does the projectile remain in the air? (in seconds) I got 3.96 s (b) At what horizontal distance from the firing point does it strike the ground? ( in meters) I...

well i put 29.75 and it said its wrong and it was my last submission so oh well, apparently 7.61 times 3.91 doesn't work.

x=v of x times t

what did u get then? because I am totally lost like i knew what i was doing for the first 2 parts but not this part.

13.12 m for the position as a function of time and 17.34 m/s as the velocity as a function of time.

Entering the Freeway. A car sits in an entrance ramp to a freeway, waiting for a break in the traffic. The driver sees a small gap between a van and an 18-wheel truck and accelerates with constant acceleration along the ramp and onto the freeway. The car starts from rest, moves in a straight...

i wrote an actual number for position as a function of time and velocity as a function of time and got it wrong
