Question

A projectile starts from rest and moves 6.1 m
down a frictionless ramp inclined at 12◦ with
the horizontal.
The acceleration of gravity is 9.8 m/s
With what speed will it leave the ramp?
Answer in units of m/s.

Answer 1

90-12=?

Answer 2

Response plz. I wanna help u

Answer 3

I am not so sure how to solve the problem

Answer 4

Ok

Answer 5

90-13=78degree

Answer 6

So ramp makes angle 78 degree with vertical.
Right?

Answer 7

Now the component of g along the ramp is
g*cos78=?

Answer 8

If u feel confusion then i will give u an attachment

Answer 9

can you please give me an attachment I still don't understand

Answer 10

Ok

Answer 11

Actuallh i m frm an android phone. So little difficult to draw

its okay, dont worry. Can you try to explain it?

Answer 13

Plz c my attachment

Answer 14

I see what you have done, I just dont understand why its like that

Answer 15

Its an inclined plane.
Right?

Answer 16

For a free fall body acceleration will b g
Right?

Answer 17

N for inclined plane acceleration will b less than g

Answer 18

okay

Answer 19

Aceelerstion along inclined plane will b a component of g

Answer 20

right

Answer 21

Feel free to ask if u hv any more confusion
