What force would a bowler have to exert on a 6-kg bowling ball to cause it to
accelerate at the rate of 4 m/s?

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude

Aparticle initially moving east with a speed of 20.0 m/s, experiences an acceleration of 3.95 m/s, north for a time of 8.00 s. what was the speed of the particle after this acceleration, in units of m/s? give the answer as a positive number.

The combining of light nuclei is called blank. blank as in not actually blank. you know what im tryin to say.
