A shell is fired at an angle of 20 degree to , an above, the horizontal from the top of a cliff 90 meter high , the velocity of the shell is 150 meter per second, calculate the distance from the foot of the cliff where it strikes the ground and 2) calculate the highest point above the ground reach by the shell

A 5 kg particle moving along the x-axis experiences the Net Force F_x = 10t, where t is in seconds. The particle has a velocity of 2 m/s at t = 1s. Find the particle's velocity at t = 5s:

a. 24 m/s

b. 26 m/s

c. 27 m/s

d. 25 m/s

how to determine the magnitude in m/s² and direction of the acceleration of the mass is external vertical force is acting

A hovercraft passes point A moving west with a speed of 15m/seconds. The hovercraft begins to accelerate at a steady rate of 2m/sec² east. How long is it before the hovercraft passes point A moving east and with what speed it will be moving as it does so?
