The magnitude of the velocity of a projectile when it is at its maximum height above ground level is 10.0 m/s. (a) What is the magnitude of the velocity of the projectile 1.00 s before it achieves its maximum height? (b) What is the magnitude of the velocity of the projectile 1.00 s after it achieves its maximum height? If we take x = 0 and y = 0 to be at the point of maximum height and positive x to be in the direction of the velocity there, what are the (c) x coordinate and (d) y coordinate of the projectile 1.00 s before it reaches its maximum height and the (e) x coordinate and (f) y coordinate 1.0 s after it reaches its maximum height?

A Chinook (King) salmon (Genus Oncorynchus) can jump out of water with a speed of 5.55 m/s. If the salmon is in a stream with water speed equal to 1.65 m/s, how high in the air can the fish jump if it leaves the water traveling vertically upwards relative to the Earth?

A man stands on the roof of a 15.0 m tall building and throws a rock with a speed of 30.0 m/s at an angle of 35° above the horizontal. Ignore air resistance. Calculate (a) the maximum height above the roof that the rock reaches. (b) the speed of the rock just before it strikes the ground; and (c) the horizontal range from the base of the building to the point where the rock strikes the ground.

A projectile is fired from point A at the edge of a cliff, whose initial velocity components are v0x = 60.0m / s and v0y = 175m / s. The projectile rises and then falls into the sea at point P. The projectile flight time is 40.0s and it does not experience appreciable air resistance in flight. a) Make a diagram of the problem, b) Determine how far it falls, c) what is the height of the cliff? and d) at what angle was it shot?

A lunar lander is descending toward the moon’s surface.Until the lander reaches the surface, its height above the surface of themoon is given by y(t) = b - ct + dt2, where b = 800 m is the initialheight of the lander above the surface, c = 60.0 m/s, and d = 1.05 m/s2.(a) What is the initial velocity of the lander, at t = 0? (b) What is thevelocity of the lander just before it reaches the lunar surface?

The acceleration vector of a particle is giving by a = -27 t2 j m/s4.  The particle is located at the origin at t = 0 s and has an initial velocity Vo = 2(m/s) i + 3(m/s) j. Find:  a) The velocity of the particle as a function of time.  b) The maximum height the particle reaches.

A particle moves in xy plane with a constant acceleration. At t = 0 the particle at r = (4.0m)ỉ + (3.0m)j, with velocity Vo. At t = 2.0s the particle has moved to r = (10.0m)ï – (2.0m)j and its velocity has changed to v; = (5.0")i- (6.0")j. a) Find the initial velocity of the particle vo. b) What is the acceleration of the particle ã? c) What is the velocity of the particle as a function of time i(t)? d) What is the position vector of the particle as a function of time 7(t)?

Question 5 5. A horizontal projectile is shot with an initial velocity of 15 m/s from a height of 3.46 m above the ground. Neglecting air-resistance, what is the magnitude of the final velocity (m/s)?
