A projectile is launched horizontally from a 20-m tall edifice with a vox of 25 m/s. How long will it take for the projectile to hit the ground?
A projectile is launched horizontally from a 20-m tall edifice with a vox of 25 m/s. Calculate the range.
A projectile is launched horizontally from a 20-m tall edifice with a vox of 25 m/s. What is the velocity of the projectile along the x axis right before hitting the ground?
A projectile is launched horizontally from a 20-m tall edifice with a vox of 25 m/s. What is the final velocity of the projectile along the y axis right before hitting the ground?
A falling body has an initial velocity of 200cm/sec.How far will it drop before its velocity becomes 10,000cm/sec
Two equal positive point charges q1=q2=2µC interact with a third point charge q3=4µC. Find
the magnitude and direction of the total (net) force on q3. (q1 is 0.3m above the origin; q2 is
0.3m below the origin; q3 is 0.4m right from the origin).
Construct your own theoretical model including numerical calculations and physical (process)to continuously charge the earth, if the currents(About 1800 A) from atmosphere tend to flow towards it?
( Else earth must get neutralized within about half an hour)
In the figure here, a red car and a green car move toward each other in adjacent lanes and parallel to an x axis. At time t = 0, the red car is at xr = 0 and the green car is at xg = 213 m. If the red car has a constant velocity of 22.0 km/h, the cars pass each other at x = 43.6 m. On the other hand, if the red car has a constant velocity of 44.0 km/h, they pass each other at x = 76.7 m. What are (a) the initial velocity and (b) the (constant) acceleration of the green car? Include the signs.
The sides of a cube are measured with calipers. The measured length of each side is (30.0 ± 0.1) mm. The measurements are used to calculate the volume of the cube. What is the percentage uncertainty in the calculated value of the volume?
A swimmer aids his body north directly across a 80m river at a speed of 12m/s. If the river is moving west at 0.7m/s. How far down stream will he land and how long will it take him to cross the river
