A proton in a cyclotron changes its velocity from 30 `kmh^(–1)` the north of 45 `kmh^(–1)` the east in 20 s. What is the magnitude of average acceleration during this time ?

A proton in a cyclotron changes its velocity from 30 kms^(–1) the north of 40 kms^(–1) the east in 20 s. What is the magnitude of average acceleration during this time ?

A particle is moving east wards with a velocity of 5 ms^(-1) In 10 S , the velocity changes to 5 ms^(-1) north wards. The average acceleration in this time is

Find the acceleration of the car, if it changes its velocity from 20 m s^(-1) to 30 ms^(-1) in 5 seconds.

A particle is moving east wards with a velocity of 15 ms^(-1) . In a time of 10 s, the velocity changes to 15 ms^(-1) northwards. Average acceleration during this time is (in ms^(-2))
