To find the initial vertical velocity, v. y, use the formula v y = -gt, where g is the acceleration of gravity and t is the time for the upward trip of the ball only. Use g = -9.81 m/s2 and one-half of the total time in the air.

A 65.0 kg trampoline performer stands on a platform 3.0 m above the trampoline as shown in the figure. If the performer jumps with an initial vertical velocity of 5.0 m/s, Find his speed as he impacts the trampoline (9.2 m/s) If the trampoline behaves like a spring with a spring constant of 6.2 x 104 N/m, how far will the trampoline be compressed?

To find it, we will exploit Eq.(6), substituting it into Eq.(2) for the motion in x-direction. This gives. The maximum horizontal range of a projectile. This may be found from Eq.(7), if we resolve the initial velocity into components in terms of the projection angle,. We substitute this into Eq.(7) and obtain. Now we use the trigonometric formula

A projectile is a particle that is given an initial velocity, but then moves under the action of its weight alone, that is all other forces are ignored. Real objects such as balls and bullets can be modelled as projectiles. The motion of a projectile can be studied by splitting it into two components: horizontal motion and vertical motion.
