could you please solve it with shiwing the full work
1-
A high powered projectile is fired horizontally from the top of a cliff at a speed of 638.6 m/s. Determine the magnitude of the velocity (in m/s) after 5 seconds.
Take gravitational acceleration to be 9.81 m/s2.
2-
A man throws a ball with a velocity of 20.9 m/s upwards at 33.2° to the horizontal. At what vertical distance above the release height (in metres) will the ball strike a wall 13.0 m away ?
Take gravitational acceleration to be 9.81 m/s2.
3-
A particle is moving along a straight path and its position is
defined by the equation s = (1t3 + -5t2 + 3) m, where t is measured
in seconds. Determine the average velocity (in m/s) of the particle
when t = 5 seconds.
4-
A particle has an initial speed of 26 m/s. The particle undergoes a
deceleration of a = (-9t) m/s2, where t is measured in seconds.
Determine the distance (in metres) the particle travels before it
stops. When t = 0, s = 0.
