Recall elmer trett, who in 1994 reached a speed of 103m/s on his motorcycle. suppose trett drives off a horizontal ramp at this velocity and lands a horizontal distance of 40.0m away from the edge of the ramp. what is the height of ramp?

Speed of the motor cycle is given as

distance that he moved off from the ramp is given as

now we know that

now we can use this to find the height

so its height will be 75 cm from ground

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

i think its c if i'm wrong
