Nice try! Find an upper-class student to give you one-on-one tutoring with your homework assignment.

P.S. This is a "trick" question -- when a human-body strikes the hard ground, it will lose (not "loose") 100% of its velocity.

When a human-body contacts something fluid, such as water, then it's possible that it will lose 25% or 50% or 75% of its velocity, and continue to dive _below_ the surface of the water.

If two balls of different masses are thrown vertically upwards with same initial speed then which one rises to a greater height?


This the problem of a projectile motion.
Assume the positive direction of the vertical axis is upward.
Let y_0 be the initial height, which we set=0.
Let v_0 be the initial velocity, a the acceleration, t the time, y the position at instant t, v the vertical velocity.
a=-g
v=v_0-gt
y=v_0*t-(1/2)*(g*t^2)
At what time is the highest point reached?
At the culmination point (highest point) the speed passes through the value 0. This happens at the time t_c given by
v_0-g*t_c=0 or t_c=v_0/g
Substitute this value in the equation for the position
y_c=v_0*t_c-(1/2)g*(t_c)^2
this gives y_c=(1/2*g)*(v_0)^2
As you can see the mass does not appear anywhere in this problem. Both masses will reach the same height.

laptop monitors can become disabled if they are dropped on the ground or in other ways mis-handled, in some cases the monitor panel has to be replaced, but it could be something as easy as reconnecting a loose connector between the motherboard and the monitor panel, any computer repair shop can assist you with this.

Depends on how long it has been travelling. If it is horizontal when it's been caught then ot must have reached zero velocity. No matter the angle gravity works at 1m/s/s. Do the math.
