How Do You Solve Projectile Motion Problems Without Specific Values?

AI Thread Summary
To solve projectile motion problems without specific values, it's essential to interpret the conditions of the equations provided. The initial height of the object can be determined by evaluating the function at time t = 0. For the time in the air before hitting the ground, one must set the height equation to zero and solve for t. The maximum height occurs when the velocity is zero, which can be found using the initial velocity and acceleration due to gravity. Understanding these concepts allows for solving the questions conceptually, even without numerical values.

Confused :( Can someone please help meee?

The height of an object above the ground at time t is given by
s = vo t - (g/2)t^2
where vo is the initial velocity and g is the acceleration due to gravity.

a) At what height is the object initially?
b) How long is the object in the air before it hits the ground?
c) When will the object reach its maximum height?
d) What is that maximum height?

I don't know how to attempt this question.. cause I haven't been given any numbers...

You aren't explicitly given any numbers, so you have to interpret what the conditions are for each question. For the first one, it asks what the initial height of the object is. What is the time (t = ?) initially? (That is, when do we start counting from?)
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
