Answer:
2.5 m/s^2
Explanation:
the formula for acceleration (or the one you use in this case) is a=vf-vi/t
where vf is equal to final velocity, vi is equal to initial velocity, and t is equal to time.
vf= 25 m/s
vi= 0m/s
t=10s 25-0=25, 25/10=2.5 therefore it is 2.5m/s^2
Answer:
(a) 
(b) 
Explanation:
Given data

Solution
For Part (a)
As the velocity component in direction of y is given by:

The maximum displacement is given by:

For Part (b)
To reach y=46cm =0.46m apply:

Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle's motion. It gives the particle the same acceleration as all those actual forces together as described by the Newton's second law of motion.
The expression 75 meters per second southeast best describe velocity as it involves magnitude and direction. From the example, the magnitude is 75 m/s (also know as speed) and the direction is southeast. Both are needed to define velocity — usually this happens to moving vehicles or automobiles.
