A 78g basketball is launched at an angle is 52.4 degrees from a distance of 14.7 m from the basket. Ball is released at the same height as basket (10 feet). Acceleration is 9.8 m/s2. What speed will the player need to give the ball? I know that I'm supposed to use the kinematics and trig to...

I just had the idea that the initial velocity would be 0 m/s

There are two of them that includes all three given variables, but they also include acceleration and initial velocity, which I don't have. How do I solve for two unknown variables?

If problem states "acceleration is constant" what is the acceleration? While gliding down a steep hill, a bike rider experiences constant acceleration. After 4.50 seconds, he reaches a final velocity of 7.50 m/sec. The bike's displacement was 19.0 meters. I know that I'm supposed to be using...

IT just hit me...the acceleration is 0 because the vel is constant! :) Thanks both of you!

Would it be 0-60 over time?

constant velocity means acceleration is 0 doesn't it because the velocity isn't changing

Enlighten me, I don't have my book with me. I guess I'm still confused about speed, vel, and acc

The car probably started at 0km/h, then speeds up to 60km/h where it stayed for 5.3hr

I'm not understanding what your asking. The acceleration is (60-0)/time right?

A car travels in a straight line for 5.3 h at a constant speed of 60 km/h. What is its acceleration? Answer in units of m/s2 So far, to my understanding so far acceleration is change in velocity over time. So 60 over 5.3, which is 11.32 km/h2 Then I converted to m first, which is 1132...
