I'm having problems of calculating the acceleration and velocity of a cart traveling down an inclined plane. I also need help calculating Sin theta. I've used 2 formulas to try calculating the acceleration and i get different answers. the first formula is a=2s/t2(squared), the 2nd formula was a=gsintheta. As for the angle sintheta i used the height of the plane/length of the board but i get ridiculous answers.
Length of inclined plane: 150.5cm
Point at which the cart is released: 115cm
Weight of cart: 784.30g
1st, height of the plane was 10 cm, avg time was 2.573 a=? v=?
2nd, height 20cm, avg time 1.483 a=? v=?
3rd, height 30cm, avg time 1.1783 a=? v=?
4th, height 40cm, avg time 0.973 a=? v=?
5th, height 50cm, avg time 0.8716 a=? v=?
6th, height 60cm, avg time 0.783 a=? v=?
7th, height 70cm, avg time 0.723 a=? v=?
8th, height 100cm, avg time 0.58 a=? v=?
Would appreciate it very much if someone could help me. I've been stuck at this for a week now and its getting really frustrating. Thank you!
